Strait of Hormuz Tensions

UKMTO reported that an LPG tanker near the Strait of Hormuz was struck by debris from unknown projectiles. The master reported all crew safe and no environmental impact, and the vessel was to proceed to its next port of call. UKMTO did not name the vessel, identify the projectiles' origin, or assign responsibility, and called on ships in the area to exercise caution and report suspicious activity. This was reported as the second UKMTO-logged Strait of Hormuz incident of the day, following a separate 21 September projectile strike on an inbound tanker.

UKMTO reported that a tanker conducting an inbound transit of the Strait of Hormuz was struck by an unknown projectile, injuring two crew members. The vessel retained power and continued to its destination port; no environmental impact was reported. UKMTO did not name the vessel, identify the projectile, or assign responsibility, and advised ships in the area to remain vigilant and report suspicious activity. Authorities were reported to be investigating.

Iran's IRGC Navy said it struck the Togo-flagged oil tanker TREND in the Strait of Hormuz on the evening of 17 September, describing the vessel as attempting an "illegal passage" and alleging it had been "deceived and provoked" by U.S. forces. The IRGC said the tanker caught fire and came to a halt after the strike. Arab News, Al Arabiya, Middle East Eye, Israel National News and Xinhua all carried the IRGC's own statement on 17-18 September, but none of the reviewed reporting cited UKMTO, CENTCOM, an operator, insurer or independent vessel-tracking service confirming the strike, the fire, a halted vessel or any casualties. This record is therefore an attributed IRGC claim only, consistent with the site's treatment of the EL GAIA and ROMANCE incidents above and below: it does not establish that a strike occurred, that a fire actually broke out, or that TREND is a real, identifiable vessel at a specific location. It will be updated if UKMTO, CENTCOM or ship-tracking data corroborate or dispute the claim.

UK Maritime Trade Operations Warning 137-26 reported a security incident approximately 16 nautical miles northeast of Khasab, Oman, on 17 September. UKMTO said the crew had been reported safe and no environmental impact had been confirmed at the time of the report, while authorities were investigating. The warning did not name the vessel, its flag, operator or cargo, nor did it specify the nature of the incident (for example whether the vessel was struck by a projectile, approached, or otherwise threatened); vessels were advised to transit with caution. This record is separate from the IRGC's own claim of striking the tanker TREND on the same date, since the two have not been linked in any reviewed reporting.

Iranian state media (IRNA, Tasnim, Press TV) said the IRGC Navy struck the Togo-flagged oil tanker Trend in the Strait of Hormuz on 17 September for attempting an "illegal passage" outside Iran's preferred shipping corridor, and that the tanker caught fire and was halted. The UKMTO separately reported a security incident in the same general area involving a tanker struck by an unknown projectile, with a fire that was extinguished and all crew reported safe, but did not identify the vessel, so independent confirmation that this is the same ship is incomplete. Details on the tanker's cargo, crew and any casualties were not immediately available. No fatalities were reported by any source. Strait transit reportedly fell sharply that day, with only 4 vessels crossing versus a roughly 16-vessel ten-day average.

UK Maritime Trade Operations Warning 135-26, issued on 15 September from a verified source, records a delayed report that a vessel was struck by an unknown projectile in the Strait of Hormuz on 14 September at approximately 20:04 UTC. UKMTO said no damage or environmental impact had been reported and authorities were investigating. The vessel's name, class, cargo, crew status, exact position, projectile type and attacker were not disclosed. This is a distinct advisory from Warning 134-26, which concerned a strike first reported on 12 September, but the limited identification means the reports cannot yet be proven to involve different physical vessels. This record does not count an additional oil tanker as damaged. The marker is a broad Strait reference, not an impact coordinate.

Iranian state media said an unidentified Iranian commercial cargo vessel was struck by an unknown projectile in waters between Hengam Island and the Shib Deraz coast of Qeshm Island early on 13 September. Qeshm Governor Hossein Amir Teymouri was reported as saying one member of the ten-person crew was killed and four were wounded; he blamed a 'terrorist enemy', but the projectile and attacker had not been identified. UK Maritime Trade Operations Warning 134-26 separately recorded a projectile strike on a vessel transiting the Strait of Hormuz, first reported at 23:00 UTC on 12 September. Update 001 said a fire subsequently broke out and local authorities were evacuating the crew. Associated Press described the Iranian casualty report and UKMTO warning separately, and no reviewed source conclusively established that they concern the same ship. This record therefore includes the UKMTO update as potentially related context but does not count it as an additional attack or transfer its fire and evacuation details to the Iranian vessel as established facts. The vessel's name, cargo, full damage and pollution status remain undisclosed. The marker is an approximate Hengam–Qeshm-area reference, not a verified impact coordinate.

The International Maritime Organization lists the oil tanker EL GAIA (IMO 9325336) as damaged in the Strait of Hormuz on 12 September, with pollution of unknown extent and two seafarers missing. This establishes a named vessel casualty, correcting the initial unverified 'ALGAYA' identity; it does not establish the cause, an uncontrolled fire, total vessel loss or the pollution quantity. The IRGC later claimed the tanker struck sea mines in a restricted southern route and was engulfed by fire. CENTCOM rejected the mine account, saying the vessel had been disabled by an Iranian missile in the preceding month and was struck again by an Iranian drone while stationary off Oman; CENTCOM also described towing efforts. Neither the claimed mine strike nor CENTCOM's two-strike chronology has been independently established in the reviewed reporting, and vessel tracking has raised questions about the timing. The IMO's 12 September record and these later statements must not be counted as three confirmed attacks. The marker is approximate because no verified impact coordinate was published.

UK Maritime Trade Operations received a master's report involving two unidentified vessels approximately four nautical miles west of Khasab, Oman. The reporting master said four unknown projectiles struck the two vessels about six nautical miles north of the master's position and that one vessel caught fire. Maritime-security company Vanguard Tech subsequently identified one vessel as ROMANCE, a Panama-flagged, approximately 50,000-dwt crude tanker built in 2009 and owned and managed from the UAE; this remains a company identification rather than a vessel name published by UKMTO. Vanguard reported that two projectiles struck one vessel and caused a fire before two more hit the other. The available reports do not make clear whether ROMANCE was the vessel that caught fire. The second vessel's identity and condition, both crews' status, cargoes, pollution, damage extent, projectile types and responsibility remain unreported. This entry therefore preserves the identification as reported and does not assign an attacker or count either vessel as destroyed.

Satellite imagery first showed a large smoke plume and thermal activity close to Saudi Arabia's East–West crude-oil pipeline southeast of Medina. Saudi Arabia subsequently confirmed multiple drone attacks in the Riyadh and Medina regions, reported injuries and material damage, and said the pipeline was shut as a precaution, interrupting its principal crude-export route that bypasses the Strait of Hormuz. On 14 September, two unnamed regional officials briefed on the damage told the Associated Press that most of the pipeline could remain out of service for three to five weeks, including repairs at a major pumping facility; one said partial operation may be possible while work continues. Separate Reuters-sourced reporting cited a five-to-six-week repair estimate while noting that operations could restart sooner. Neither estimate is a timetable issued by Saudi Arabia or Aramco. The Saudi Energy Ministry did not name an attacker, while the Foreign Ministry said several drones had come from Iraq without identifying the responsible group or drone model. No published wreckage analysis currently supports identifying them as Shahed, Sammad or another specific type. Iraq later said the launch site was in Maysan province, dismissed the province's operations commander and ordered an investigation into those responsible; those measures establish an Iraqi launch finding, not the identity of the operators. Iraq also closed two border crossings with Iran, while an Al Jazeera correspondent reported heavily armed forces visible on streets in Maysan. The purpose and targets of that deployment were not established, so it is recorded as a reported security response rather than evidence that any particular group had been identified. Qatar, Jordan and the Gulf Cooperation Council condemned the attack, and the GCC called on Baghdad to prevent further attacks from Iraqi territory. Satellite analysis cited by CNN showed extensive fire effects at one pumping-station site and a smaller fire at another; at least six of nine other detected heat signatures aligned with emergency flare pits and should not be counted as confirmed impacts. Later Vantor-branded high-resolution imagery circulated by MenchOsint shows widespread scorching and visibly damaged above-ground equipment across one pumping-station complex, strengthening the assessment of serious surface fire damage. OSINT613 described the more heavily affected station as completely destroyed, but neither image alone establishes total functional loss or damage to buried pipeline sections. The line has a stated maximum capacity of approximately 7 million barrels per day, but reported actual flows were roughly 4–5 million barrels per day during the first five months of the conflict and about 2 million in August. None of those figures is a confirmed production or export loss caused by the attack. The available evidence does not confirm a pipeline rupture, pollution or the volume of lost throughput. Claims of Houthi responsibility and catastrophic damage remain unverified and are not adopted here. The marker remains approximate because no verified impact coordinate has been published.

The IRGC said its naval forces targeted two U.S. vessels and eight oil tankers in the Strait of Hormuz in response to the 8 September U.S. strikes on five Iranian tankers. A statement carried by Tasnim also referred to ten 'violating ships' allegedly attempting to cross what Iran called a prohibited and unsafe zone with U.S. encouragement and support. The available wording does not make clear whether those ten ships are the same set of two U.S. vessels plus eight tankers or an additional group, so this record does not infer a twenty-vessel total. No vessel names, weapon types, precise locations, authenticated impact imagery, casualty figures or pollution assessment were supplied in the reviewed report. CENTCOM later directly rejected the IRGC's assertion that two U.S. destroyers were struck, saying no U.S. Navy warship had been hit and all attempted attacks failed. No reviewed flag-state, shipowner or independent maritime-security account confirms hits on the other claimed targets. This record therefore documents the IRGC statement and the U.S. denial, not successful strikes. The marker is a broad Strait reference and not an impact coordinate.

UK Maritime Trade Operations said it received a report involving a merchant vessel in the Strait of Hormuz that was subject to an unspecified 'interaction' as part of ongoing military activity in the region. UKMTO said authorities were aware and investigations remained ongoing. The advisory did not identify the vessel, its flag, cargo, precise position, the parties involved, the nature or outcome of the interaction, or any casualties, damage or environmental impact. It is therefore classified here as an investigating maritime interaction rather than a confirmed attack. Available information is also insufficient to match it to Iranian claims or other individually reported Gulf incidents, so it is not counted as a duplicate of those events. The marker is an approximate regional reference, not a reported incident coordinate.

Iranian state television said Iranian forces captured a U.S. unmanned underwater vehicle in the Strait of Hormuz and displayed it as a seized prize. CENTCOM spokesman Capt. Tim Hawkins confirmed that an Anduril Dive-LD had malfunctioned more than a day earlier and was no longer in U.S. possession, while describing it as an older commercially available configuration without sensitive data or classified sonar or radar. Reuters said it could not independently verify Iran's account of the recovery. Maritime Executive reported that close-up imagery allowed open-source identification of the vehicle as a Dive-LD. The U.S.-confirmed loss is documented; whether Iranian forces recovered it in the manner claimed remains unresolved. This was an unmanned vehicle, not a crewed submarine, and the reviewed reports identify no casualties, pollution or attack damage. The marker is approximate because neither side published recovery coordinates.

Iranian reporting said IRGC air defences shot down a U.S. unmanned aircraft over the Strait of Hormuz. Fars, as relayed by Anadolu, identified the aircraft as an MQ-1; a Sepah News account relayed by Xinhua identified it as an MQ-9 Reaper. No reviewed U.S. statement, independently authenticated wreckage or geolocated imagery confirms a loss, and the conflicting model identifications remain unresolved. The event is therefore recorded only as an unconfirmed Iranian claim. No casualties, energy-infrastructure damage or shipping disruption were reported, and the marker is a broad regional reference rather than a claimed impact coordinate.

Iran's Islamic Revolutionary Guard Corps Navy said it attacked a U.S. military unmanned surface vessel that was attempting to enter what it called a protected area of the Strait of Hormuz. Al Jazeera carried the statement at 02:30 GMT on 6 September, including an IRGC warning that the waterway was under Iranian control; that is the report time, not an established attack time. Iran did not identify the vessel, weapon, precise position or damage, and did not publish independently verifiable evidence with the announcement. CENTCOM spokesperson Capt. Tim Hawkins subsequently denied that any U.S. unmanned vessel had been struck, calling the Iranian account a “total lie.” The denial does not establish whether Iran fired at, attempted to engage or merely claimed an attack on a U.S. vessel, but it directly contradicts the claimed hit. This is therefore retained as one unconfirmed Iranian claim, not a verified vessel impact. The marker is an approximate central-Strait reference and must not be interpreted as the vessel's position.

The IRGC Navy said it attacked three oil tankers travelling on what it called an unauthorised route through the Strait of Hormuz and three U.S.-linked vessels elsewhere after U.S. forces struck the Iranian carriers Downy, Stark 1 and Kylo/Noxen. Iran did not publish the six vessels' names, flags, cargoes, precise positions, weapons, damage or casualties. No matching UKMTO warning, shipowner confirmation or independently verified imagery reviewed for this record establishes six additional impacts. The wording may overlap partly or wholly with Iran's separately recorded ballistic-missile attack on a U.S. aircraft carrier and destroyer and its disputed claim concerning a U.S. unmanned vessel. Because the available reports do not permit reliable vessel matching, this is retained as one attributed claim cluster rather than six counted attacks; it must not be used to increase the verified vessel-damage total.

Iran's Islamic Revolutionary Guard Corps said it launched several ballistic missiles toward a U.S. aircraft carrier and a U.S. Navy guided-missile destroyer that it accused of participating in the naval blockade and harassing Iranian shipping. CENTCOM independently acknowledged that an aircraft carrier and destroyer came under multiple Iranian attacks, but said both warships successfully evaded them and no U.S. personnel were harmed. A user-supplied screenshot captured on 6 September shows Open Source Intel (@Osint613) relaying the IRGC claim that missiles struck a U.S. Navy carrier and destroyer, explicitly calling the report currently unconfirmed. Its quoted earlier post, credited to @BeamTracker_, reports an IRGC Navy anti-ship ballistic-missile launch from Sirik, southern Iran, allegedly targeting vessels transiting the Strait of Hormuz outside an Iran-approved route. Confidence in the claimed hits and Sirik launch details remains unverified. The published graphic does not establish the launch time, missile type, intended vessel or outcome, and it has not been shown to represent an additional attack rather than part of the acknowledged salvo. MoloMonitor separately assessed that the episode was Iran's first attempt during the current war to strike a U.S. nuclear-powered aircraft carrier, placed the attempt in the Gulf of Oman and attributed the weapon to the approximately 300-kilometre-range Khalij Fars anti-ship ballistic-missile family. The Khalij Fars is a documented Iranian anti-ship derivative of the Fateh-110 with an assessed range of about 300 kilometres, but no official statement or independently verified debris reviewed for this record confirms that it was the weapon used, and the carrier's location remains undisclosed. MoloMonitor also relayed a Khatam al-Anbiya Central Command warning that continued U.S. blockade operations would lead Iran to increase attacks on U.S. Navy vessels and expand the scope of naval warfare; this is escalation rhetoric, not evidence of another completed attack. Anadolu, citing an IRGC statement carried by IRNA, reported the claim that the U.S. ships sustained damage and withdrew from the conflict zone; no imagery, named vessel, location, damage assessment or other independent evidence substantiated that account. A newer user-supplied live-report screenshot received on 6 September relays the IRGC statement that it launched several ballistic missiles at the two warships, which it accused of harassing Iranian vessels and participating in a naval blockade. The screenshot cites Tasnim reporting the IRGC claim that both warships sustained damage and were forced to leave the conflict zone for fear of further attacks. This adds sourcing for the IRGC account, not independent confirmation of hits, battle damage or withdrawal; all three remain unconfirmed claims and conflict with CENTCOM's successful-evasion account. This record therefore documents the missile attack but not a verified impact. U.S. forces subsequently struck M/T Downy, M/T Stark 1 and M/T Kylo/Noxen in a separate retaliatory operation recorded elsewhere on the map. The marker is a broad regional reference and must not be interpreted as either warship's position.

Iran's IRGC Navy said it retaliated for U.S. strikes on three Iranian crude carriers by targeting three oil tankers allegedly travelling along an 'unauthorized route' through the Strait of Hormuz and three additional vessels it described as U.S.-linked elsewhere in the region. The statement did not name the vessels, provide coordinates, identify weapon types or publish evidence of impacts, casualties, damage, pollution or loss of propulsion. UKMTO Advisory 127-26 separately reported, citing military authorities, that several merchant vessels had been subjected to disabling fire in the northern Arabian Gulf and Gulf of Oman. The advisory did not publicly identify the attacker or vessels, and the available wording is insufficient to prove that it describes all or any of the six vessels in Iran's claim. This is therefore one unverified regional claim, not six confirmed vessel incidents; the marker is illustrative and not a strike coordinate.

TankerTrackers said it tagged at least 17 crude-oil, LNG and LPG ship-to-ship transfers conducted in the Gulf of Oman on 4 September, involving at least 24 million barrels. The service separately reported that vessels carrying at least 7.25 million barrels, together with two additional LNG tankers, were assembling to transit outward through the Strait of Hormuz under U.S. Central Command protection. No matching public CENTCOM statement reviewed for this record independently confirmed the protection arrangement, vessel identities, convoy timing or cargo totals, so those details remain attributed to TankerTrackers. TankerTrackers subsequently estimated that August crude exports from Saudi Arabia, Iraq, Iran and Kuwait were 39% below their combined January-February level of about 18.5 million barrels per day. It said the deficit had narrowed from 67% in May, with the August shortfall put at 7.2 million barrels per day versus 12.4 million in May; these are tracking-service estimates rather than official customs totals. Separately, South Korea's presidential office said Seoul could consider military contributions to freedom-of-navigation efforts without compromising defence readiness and subject to domestic legal procedures, while stressing that no deployment decision had been made. South Korean reporting said options under preparation could include a P-8 maritime patrol aircraft, an explosive-ordnance-disposal team and a naval logistics support ship; these remain proposed capabilities, not an active South Korean escort operation. The Strait remained severely restricted and exposed to attack, harassment and blockade activity, but was not completely closed: limited commercial transits continued. This is a maritime-flow and security update, not a new physical attack. The marker represents the wider Hormuz–Gulf of Oman operating area rather than a vessel position or transfer site.

Saudi operator Bahri confirmed that two Filipino seafarers aboard its laden VLCC SIDR were killed in a security incident while the vessel transited outbound through the Strait of Hormuz shortly before midnight local time. Oman later said its Maritime Security Center evacuated 16 of the vessel's 25 crew members; the public update did not account for the remaining seven, whose status therefore remains unknown rather than presumed dead. Shipping intelligence placed a projectile strike about 16.6 nautical miles northeast of Khasab at approximately 19:52 UTC; subsequent AIS data showed the vessel moving at about 0.6 knots, but that observation alone does not prove it was disabled. UKMTO Warning 126-26 separately described a verified, time-late tanker incident with two casualties and no reported environmental impact; the timing and casualties align with SIDR, although the public warning did not name the vessel. Associated Press described the tanker as attacked by Iran, while the earlier operator and UKMTO accounts did not publicly establish the attacker or weapon; this record preserves that distinction. Full damage and pollution status remain unconfirmed. This record is separate from the near-simultaneous SENEGAL PROSPERITY strike.

Maritime analysts cited by Reuters identified the second of two near-simultaneous VLCC attacks as the Liberian-flagged SENEGAL PROSPERITY, operated by South Korea's Sinokor and carrying about 2 million barrels of Saudi crude. UKMTO Warning 124-26 independently confirmed that an unnamed outbound tanker was struck by three unknown projectiles approximately 17 nautical miles east of Khasab at 20:00 UTC, with no casualties or environmental impact reported. Reuters-linked reporting and other maritime analysts associated that warning with SENEGAL PROSPERITY, but UKMTO did not name the vessel and some open-source accounts instead associated Warning 124-26 with SIDR. The vessel identification is therefore retained as an assessment rather than presented as an official UKMTO identification. The attacker, projectile type, damage extent and subsequent operational status remain unconfirmed.

UKMTO Advisory 123-26 said the tanker master reported an incident involving the vessel and military forces. Associated Press reported that Ambrey said the tanker had reportedly been stopped and remained adrift. No casualties were reported. The tanker, military force, reason for the encounter, damage, pollution and precise location were not identified. Because UKMTO issued an advisory rather than an attack warning, this entry does not label the encounter an attack or assign responsibility.

DISPUTED CLAIM — POSSIBLE PROPAGANDA OR MISINFORMATION. The IRGC alleged that an unidentified supertanker caught fire and stopped after striking two naval mines in the southern Strait of Hormuz. CENTCOM directly denied the account, stating that no ships had hit mines in the strait and calling the story an attempt to intimidate commercial shipping through disinformation. No vessel name, IMO number, operator statement, distress report, exact position, casualty assessment, pollution report, UKMTO notice or other independent maritime-authority confirmation has been identified. Reuters and other outlets documented the allegation but did not independently verify the vessel, mine strikes or fire. It is not recorded as an established attack.

UK Maritime Trade Operations Advisory 123-26 said a tanker master reported an incident involving the vessel and military forces in the Indian Ocean. Associated Press reported that maritime-security firm Ambrey said the tanker had reportedly been stopped and remained adrift. No casualties were reported. The advisory did not identify the tanker, flag, owner, cargo, military force, reason for the encounter, damage, pollution or precise position. UKMTO issued an advisory rather than classifying the event as an attack, so this record is an investigating shipping disruption and does not assign responsibility. The map marker is a broad illustrative Gulf of Oman position, not a reported incident coordinate.

DISPUTED CLAIM — POSSIBLE PROPAGANDA OR MISINFORMATION. Iran's Islamic Revolutionary Guard Corps said an unidentified supertanker caught fire and stopped after striking two naval mines in the southern Strait of Hormuz. CENTCOM directly denied the account, stating that no ships had hit mines in the strait and describing it as IRGC disinformation intended to intimidate commercial shipping. No vessel name, IMO number, operator statement, distress report, exact position, casualty assessment, pollution report, UKMTO notice or other independent maritime-authority confirmation has been identified. Reuters and other outlets documented the allegation but did not independently verify the vessel, mine strikes or fire. 'Supertanker' often denotes a VLCC, but even the vessel class is unconfirmed. The record preserves the information claim and the official denial; it is not presented as an established attack. The marker is only an approximate reference, not a verified incident coordinate.

US forces struck two Iranian Revolutionary Guard launchers on Larak Island after US surveillance reportedly observed personnel preparing to launch rockets carrying sea mines into the Strait of Hormuz, according to US Central Command. The strike was the first publicly reported US military action inside Iran in about a month and followed the announced clearance of mines from the strait's main international shipping routes. Iranian media initially reported two people killed and several injured. Tasnim subsequently said one injured person died in hospital, raising the Iranian-reported death toll to three; a stable final injury count has not been published. These casualty figures remain attributed to Iranian reporting rather than independently verified. Iran subsequently launched ballistic missiles toward US sites in Jordan. Iranian state television broadcast what it described as the launches, while Jordan's armed forces said its air defences intercepted eight missiles that entered Jordanian airspace early on 31 August. A US official told Axios that several missiles were launched but none struck a US base and no damage or casualties were reported. The retaliation is therefore documented as a missile launch and interception, not as a successful strike on a base or energy facility. The Larak targets were military, but the reported mine-launch preparations directly concerned the security of the Strait of Hormuz oil-shipping corridor. The public accounts did not establish the weapon used by the United States, damage beyond the two launchers or any strike on oil infrastructure. The marker remains an approximate Larak Island reference rather than a verified impact coordinate.

UK Maritime Trade Operations Warning 122-26 relayed a time-late report from military authorities that a tanker had been struck by an unknown projectile while transiting inbound approximately 12 nautical miles north of Khasab, Oman. No casualties or environmental impact were reported. The initial notice did not identify the vessel, flag, owner, cargo, damage extent, projectile type or source, and authorities were investigating. This is a separate incident from the AL SALAM II strike reported under Warning 121-26.

UK Maritime Trade Operations Warning 121-26 said local authorities reported that a tanker near Khasab had been struck by an unknown projectile, causing a fire that was subsequently extinguished. All crew were reported safe and no environmental impact was reported. The Joint Maritime Information Center later identified the eastbound vessel as the Kuwaiti-flagged AL SALAM II and reported a small breach above the waterline. Neither UKMTO nor JMIC identified the projectile type or assigned responsibility, so this record does not attribute the attack.

In Warning 120-26, UK Maritime Trade Operations said the master of an oil tanker reported that an unknown projectile struck the vessel approximately 9 nautical miles northeast of Ash Shishah, Oman. The impact damaged the engine room and disabled the tanker. The crew were reported safe, while the environmental impact was unknown at the time of the initial warning. Authorities were investigating and UKMTO did not identify the projectile's source or assign responsibility. Seatrade Maritime subsequently identified the vessel as the Liberian-flagged Aframax tanker Metro Venetian; that identification was not included in UKMTO's initial notice and is therefore retained as reported rather than official vessel confirmation.

UK Maritime Trade Operations warning 115-26 said an unidentified vessel transiting outbound near Khasab, Oman was struck by an unknown projectile, damaging the engine room and resulting in a crew casualty; the remaining crew were being assisted by the Omani Coast Guard, and no environmental impact was reported. UKMTO's own wording did not specify whether the casualty was a fatality or an injury, and secondary reporting diverged: Al Jazeera and several wire-sourced outlets described a crew member killed, while Ship & Bunker's reporting characterized it as a crew member injured. This record treats the casualty's severity as unresolved rather than asserting either account. The vessel's name, flag, type, cargo and the projectile's source were not published. It follows a run of similar unattributed projectile strikes on vessels transiting the Strait in the preceding days, including the 14 August bulk-carrier strike recorded separately on this map.

MSCIO Alert 95/26 reported that an unnamed vessel was struck by an unknown projectile during an outbound transit of the Strait of Hormuz. The impact damaged the engine room and caused one crew casualty. The Omani Coast Guard was assisting the remaining crew, and no environmental impact was reported. The preliminary alert did not publish the vessel type, name, flag, cargo, later status or attribution.

MSCIO Alert 96/26 reported that an unnamed bulk carrier was struck by an unknown projectile while transiting the Strait of Hormuz. The impact damaged the starboard side and caused one crew casualty; no environmental impact was reported. The MSCIO feed's plotted coordinates for this alert fall near Bab al-Mandeb and conflict with its written Strait of Hormuz location, so this map uses an explicitly approximate Hormuz marker rather than reproducing the inconsistent feed point. No responsibility was assigned.

ADNOC said one of its vessels was attacked while transiting the Strait of Hormuz on Friday local time, according to a CNN update citing the UAE's WAM state news agency. The company said the situation was brought under control and no injuries were reported. CNN described this as the third reported attack on ADNOC tankers in under a week. The update did not identify the vessel, attack method, attacker, damage or precise location. This record is kept separate from the two-vessel incident reported the previous day because the update explicitly described a Friday attack, but should be reconciled if later official or maritime reporting shows it referred to the earlier event.

UK Maritime Trade Operations warning 113-26 records a verified report that an unidentified bulk carrier was struck in its hull by an unknown projectile in the Strait of Hormuz. UKMTO said the crew were safe, no damage assessment had been reported and environmental impact was unknown. Al Jazeera's live coverage reported the incident occurred at about 20:00 GMT on 14 August. The vessel's name, flag, owner, cargo, exact coordinates, projectile type and attacker remain unpublished. The marker is an approximate central-Strait reference and does not represent a verified impact position; the ship is recorded as a bulk carrier, not an oil tanker.

MSCIO Alert 93/26 reported that an unnamed bulk carrier was struck by an unknown projectile in the Strait of Hormuz. The projectile impacted the hull and the crew were reported safe, while the damage assessment and environmental impact remained unknown. This is distinct from the ADNOC-affiliated vessel attack also reported on 14 August: MSCIO identified this vessel as a bulk carrier and gave an approximately 20:00 UTC incident time. No actor was identified.

The UAE said an ADNOC-affiliated tanker was targeted by an Iranian missile while transiting the Strait of Hormuz. MSCIO Alert 89/26 independently recorded a vessel struck by an unknown projectile about 18 nautical miles east of Khasab at the same date and location; the impact caused a fire that was extinguished, and the vessel and crew were reported safe with no environmental damage. The official reports did not explicitly name the MSCIO vessel as the ADNOC tanker, so that match is retained as probable rather than certain. Regional governments (Qatar, Saudi Arabia, Bahrain, the GCC) condemned the strike. ADNOC said this was one of a rising number of attacks on its vessels since the US–Iran war closed the strait to normal traffic in February 2026. A separate, earlier July 2026 strike on the tankers Mombasa and Al Bahiyah did cause one fatality — that is a distinct, already-documented incident, not this one.

A vessel belonging to the Abu Dhabi National Oil Company (ADNOC) was targeted by a missile while transiting the Strait of Hormuz, the UAE's WAM state news agency initially reported without identifying an attacker. The UAE Ministry of Foreign Affairs subsequently accused Iran of the strike, describing it as an act of piracy by Iran's Revolutionary Guard Corps (IRGC) and demanding Tehran halt the attacks and reopen the strait fully and unconditionally; ADNOC confirmed one of its ships was targeted by a missile but did not detail damage or the vessel's exact location. No casualties were reported. The attack drew swift condemnation from Gulf and Arab governments: the Gulf Cooperation Council's secretary-general called it a 'dangerous and unacceptable escalation'; Qatar and Saudi Arabia condemned it and demanded the strait reopen without conditions, with Riyadh calling it a grave breach of international law and UN Security Council Resolution 2817; Jordan called it a flagrant violation of international law; and Bahrain's Ministry of Foreign Affairs said it violated international law, the UN Convention on the Law of the Sea and Resolution 2817, affirmed full solidarity with the UAE, and urged the UN Security Council to take decisive measures. It follows ADNOC's own statement the previous day (7 August) that 15 of its vessels had been attacked by missiles and drones since the war began, including three that week alone, resulting in one fatality and 20 injuries; this new attack is separate from and not yet included in that count.

MSCIO Alert 88/26 said the master of an unnamed tanker heard two explosions while transiting about 9 nautical miles southeast of Kumzar, Oman. The vessel and crew were confirmed safe and no environmental damage was reported. MSCIO classified the report as an attack alert, but said the source and cause of the explosions remained unknown. Because the alert did not report a projectile sighting, impact or damage, this record is classified as an attack threat under investigation rather than a confirmed strike.

Satellite imagery acquired on 10 August and analysed by the United Nations University Institute for Water, Environment and Health mapped approximately 100 square kilometres of oil-contaminated water around Qeshm and Hengam islands at the boundary of the Persian Gulf and Gulf of Oman. Dark oily residue reached Qeshm's southern shoreline and was reported inside the Hara mangrove ecosystem. The damaged Liberia-flagged bulk carrier Minoan Pioneer, struck near the Strait of Hormuz on 3 August, is considered the likely source of at least part of the pollution based on satellite and vessel-tracking analysis. That source link is retained as likely rather than conclusive: the IMO lists pollution from Minoan Pioneer as unconfirmed, and no completed official investigation or measured release volume was available. Iran reported that cleanup had largely removed visible shoreline oil by 12–13 August, but monitoring continued. The ecological exposure includes coral reefs, tidal flats, fish nursery habitat, migratory birds, green turtles and critically endangered hawksbill turtles; oil retained in fine mangrove sediment and root systems can persist after the surface slick is no longer visible. The marker represents the polluted Qeshm–Hengam coastal area rather than the vessel's precise attack location.

MSCIO Alert 86/26 reported that an unnamed cargo vessel broadcast on VHF Channel 16 that it had been struck by an unknown projectile about 20 nautical miles northeast of Khasab, Oman. The vessel suffered a complete blackout and required assistance. The preliminary public alert did not identify the ship, cargo, projectile source, crew condition, damage extent, pollution or later operating status, and assigned no responsibility.

The Bermuda-flagged LNG carrier GasLog Shanghai was struck by an unidentified projectile while departing the Strait of Hormuz, about 11 nautical miles northeast of Limah, Oman. The strike damaged the engine room, causing a fire the crew extinguished and a temporary blackout that left the vessel not under command. GasLog said everyone aboard was safe and the vessel was stable, and activated its emergency response plan without disclosing the extent of the damage. The incident came within about an hour of a separate UKMTO report of a large splash and explosion near another tanker 21 NM northeast of Khasab, Oman, which reported no damage; it was not immediately clear if the two were connected.

Saudi Arabia confirmed that its tanker Wedyan was targeted while transiting the Strait of Hormuz. Maritime reporting described damage to a VLCC, with the crew safe and no environmental impact reported.

The laden Qatari LNG carrier was struck while transiting south through the Strait of Hormuz. The crew was evacuated without reported injury and no environmental impact was reported.

Kiku was struck while transiting the Strait of Hormuz, damaging its bridge. All crew were reported safe and no oil leak or other environmental impact was reported.

The US-flagged tanker, part of the US Maritime Administration's Tanker Security Program, was struck by two missiles around 2 a.m. local time while in dry dock for planned maintenance at a Bahrain shipyard. The crew evacuated safely; one shipyard worker was killed and two others were seriously injured. A fire caused by the strikes was quickly extinguished. In February 2026 the same vessel had been harassed by IRGC fast boats while transiting the Strait of Hormuz under US Navy escort.

The tanker, flying the flag of Palau despite having been deregistered by that country, was struck by a projectile while at anchor near Khasab on the Musandam Peninsula, catching fire. Reuters reported two crew members dead and four injured; the vessel was evacuated. It was among the first tankers hit as the 2026 Strait of Hormuz crisis began.

The UAE said two ADNOC-affiliated vessels were targeted while transiting the Strait of Hormuz, the second reported attack on ADNOC shipping within a week. No injuries were reported. The UAE Ministry of Foreign Affairs called it an act of piracy by Iran's Revolutionary Guard Corps and a violation of UN Security Council Resolution 2817; Bahrain expressed solidarity with the UAE. At 01:00 GMT on 15 August, Al Jazeera reported that Saudi Arabia's Foreign Ministry had issued its strongest condemnation of the attacks, described their recurrence as a dangerous escalation and direct threat to maritime navigation and global energy supplies, held Iran fully responsible for the consequences, and reiterated Saudi solidarity with the UAE. ADNOC said 15 of its vessels have now been attacked since the Strait effectively closed to normal traffic in February 2026. UKMTO separately confirmed, in a warning notice issued 14 August citing military authorities, that a tanker was struck by an uncrewed aerial vehicle (UAV) at 15:52 UTC on 13 August while conducting an outbound transit of the Strait; the vessel sustained minor damage, the crew were reported safe and accounted for, and no environmental impact was reported. UKMTO's advisory did not name the vessel or explicitly link it to the ADNOC statement, but the timing and location match one of the two ADNOC-affiliated vessels reported hit that evening, so this record treats the UKMTO advisory as adding detail to the same incident rather than a separate one.

UK Maritime Trade Operations (UKMTO) said a tanker transiting westbound in the Gulf of Aden, about 136 nautical miles east of Al Mukalla, Yemen, broadcast a distress call on VHF channel 16 after being approached by an unauthorised vessel; six armed people subsequently boarded and took control of the ship, redirecting it toward Somalia. UKMTO confirmed the boarding and said authorities were investigating, but gave no further details on the crew's safety or the vessel's condition. Monitoring outlets identified the vessel as the tanker Seamull, also referred to as SIBU 1. Just Security, summarising New York Times reporting, described it as a suspected Iranian shadow-fleet tanker; that characterisation is not independently established in the UKMTO advisory and is retained as reported context rather than confirmed ownership or trading status. Al Jazeera reported the hijacking as part of a wider resurgence of Somali piracy in 2026, noting that at least five ships remained under pirate control at the time, with the most recent prior hijacking the preceding Monday, and linked the trend to naval forces being stretched thin by the concurrent Red Sea and Strait of Hormuz conflicts, pushing more shipping traffic closer to Somali waters. This is a distinct incident from the 17 July 2026 UKMTO 090-26 hijack recorded separately on this map, which involved a different tanker boarded roughly 65 nautical miles south (not east) of Al Mukalla.

Iranian Foreign Ministry spokesperson Esmail Baghaei said Iran would not reopen the Strait of Hormuz until the United States met Tehran's conditions, including ending the blockade of Iranian ports, lifting sanctions, releasing frozen Iranian assets and compensating Iran for war damage. President Donald Trump rejected the demand and said he would instead require Iran to compensate Americans killed or wounded in attacks attributed by the US government to Iran-backed groups, as well as families of Iranian protesters. The statements did not establish an agreement or reopening date. The strait's continuing restriction remained a major energy-market disruption because roughly one-fifth of internationally traded oil passed through it before the war. This is a regional political and shipping-disruption marker, not a new physical attack or a claim that traffic had stopped completely.

US Department of Energy data showed crude stocks in the Strategic Petroleum Reserve fell by 6.1 million barrels during the week to 298.7 million barrels, taking the reserve below 300 million barrels for the first time since 1983. The four-site Gulf Coast system has about 714 million barrels of authorised storage capacity and held about 415 million barrels when the Iran war began. The draw formed part of a planned 172-million-barrel US release during 2026 after disruption to shipping through the Strait of Hormuz; CNBC reported that the reserve would fall to roughly 243 million barrels if the release were completed. A May 2026 Government Accountability Office report found that more than a quarter of the reserve's authorised capacity was unavailable at the end of 2025 because of construction work and cavern outages, while Rapidan Energy Group estimated for CNBC that at least 103 million barrels of the inventory then held could not be accessed immediately. The Energy Department described roughly 70 million barrels as the safe operational minimum, but aging infrastructure and ongoing construction can constrain practical withdrawal rates before that floor is reached. This is a national supply-security milestone and infrastructure-availability incident, not a physical accident, attack or claim that Bryan Mound alone holds the reported total; the marker is anchored at Bryan Mound as the largest of the four SPR storage sites.

UK Maritime Trade Operations said the Middle East maritime threat level remained severe as attacks and harassment of commercial shipping persisted in the Strait of Hormuz. The agency described IRGC-linked activity including VHF hailing, UAV overflight and targeted surveillance of merchant vessels, and said kinetic activity—including projectile strikes and near-miss explosions—continued along the southern Omani approaches around Limah, Khasab and Kumzar. UKMTO also warned of a continuing risk from drifting and uncharted mines. Commercial traffic through the strait remained at reduced levels, with transits in the single digits. This is a regional campaign and threat-assessment marker rather than a claim that each described interaction was a separately verified attack. The UAE/ADNOC tanker hit on Saturday, 8 August, is already recorded as its own incident and is not duplicated here. The marker is an approximate reference point for the southern approaches, not a precise event location.

US Central Command said that as of 11 September it had redirected 99 commercial vessels while enforcing the resumed US blockade against Iran. That updates the redirected tally of 59 published on 12 August; the latest post, as relayed in live coverage, did not supply updated disabled or boarded totals. CENTCOM has repeatedly said the Strait of Hormuz remains open for commercial transit while enforcing restrictions on traffic to Iranian ports, although traffic remains severely reduced. Iran separately announced that representatives from Iran, Iraq and Gulf states would meet in Oman on Monday to discuss shared regional security and possible safe shipping routes through the strait. That is a planned diplomatic meeting, not evidence that a safe corridor has opened or that the blockade has ended. This tally belongs to the phase CENTCOM said resumed on 14 July and is not combined with the larger totals it reported during the earlier April–June phase. It is represented by one approximate regional marker because CENTCOM did not identify every redirected vessel or publish a location for each interaction. CENTCOM's characterization of vessels as blockade violators is attributed to the US government; the statement did not establish that all vessels were tankers or disclose every cargo, crew condition, damage detail, environmental effect or the legal basis of each individual action.

Reuters reported, citing ship-tracking data from Kpler, that shipping traffic through the Strait of Hormuz and Bab al-Mandeb was little changed on Tuesday (4 August) from the previous day and remained far below pre-war levels. Eight vessels — five tankers and three bulk carriers — transited Hormuz, with six entering and two (a gas carrier and a tanker) exiting; roughly 130 to 140 ships would typically transit the strait before the US-Israeli war on Iran began on 28 February and Iran responded by closing it. In Bab al-Mandeb, 20 vessels crossed (10 each way), the same as the previous day; crossings there averaged about 41 vessels a day in the week before the Houthis declared their 20 July maritime blockade of Saudi Arabia. Kpler and LSEG data separately showed the ADNOC-controlled LNG tanker Mubaraz reappearing outside the strait, having departed Das Island, UAE, on 14 July and last been seen inside the strait on 16 July, now off India's western coast en route to the Dahej terminal — the third cargo it has carried out of the strait since the war began. Some vessels transiting with transponders off are not captured in these counts.

Iranian media, including the IRGC-linked Tasnim news agency, reported that an unidentified oil tanker exploded after striking a naval mine when it deviated from a route designated by Iranian authorities in the Strait of Hormuz. Al Jazeera reported the claim from Tehran, and Reuters relayed Tasnim’s account. At the time reviewed, no vessel name, flag, owner, voyage, cargo, precise position, imagery, crew condition, pollution assessment, or independent maritime-security confirmation was available. The occurrence of an explosion and the asserted mine cause therefore remain unverified. The marker is approximate and does not indicate a confirmed mine location.

UKMTO received a report of an incident approximately 20 nautical miles northeast of Al Khasab, Oman. A cargo vessel broadcast on VHF channel 16 that it had been hit by an unknown projectile. Authorities were investigating at the time of the notice. The vessel identity, cargo, projectile source, damage, and responsibility were not established in the notice.

UKMTO received a report of an incident approximately 20 nautical miles northeast of Khasab, Oman. The Master of a tanker reported hearing an explosion in close proximity to the vessel; the vessel and crew were reported safe. Authorities were investigating at the time of the notice. The vessel identity, cargo, explosion source, and responsibility were not established in the notice.

UKMTO received a report from a tanker's Master describing an incident approximately 21 nautical miles northeast of Khasab, Oman. The Master reported seeing a large splash and explosion in close proximity to the vessel; no damage to the vessel had been reported at the time of the notice. The vessel identity, cargo, explosion source, and responsibility were not established in the notice.

UKMTO received a report of an incident 11 nautical miles northeast of Lima, Oman. The tanker's company security officer reported that the vessel had been struck by an unknown projectile that damaged the engine room, leaving the tanker not under command. The regional Coast Guard was informed. No casualties or environmental impact were reported. The UKMTO notice itself did not establish the vessel's identity, cargo, projectile source, or responsibility, but GasLog subsequently confirmed the tanker involved was its Bermuda-flagged LNG carrier Gaslog Shanghai, struck while departing the strait on 31 July; the company said everyone aboard was safe and accounted for and the vessel was stable, without disclosing the nature or extent of the damage. It was the second Qatari-cargo LNG carrier hit in the Strait of Hormuz within a month, after the Al Rekayyat on 6 July.

UKMTO received a time-late report of an incident 9 nautical miles southeast of Kumzar, Oman. The Master of a tanker transiting the Strait of Hormuz reported hearing two explosions. The report confirmed crew and vessel were safe, with no environmental damage reported. Vessels were advised to transit with caution and report any suspicious activity. The vessel identity, cargo, explosion source, and responsibility were not established in the warning.

UKMTO received multiple reports that a tanker reported over VHF Channel 16 that an unknown projectile had struck it in the Strait of Hormuz. The company security officer later reported that the crew had abandoned the vessel and were in a lifeboat. No environmental impact was reported. The vessel identity, damage extent, projectile source, responsibility, and casualty status were not established in the notice.

UKMTO initially received information from military authorities that a vessel was on fire, with the cause unverified. UKMTO later reclassified the incident as an attack after the company security officer confirmed that an unknown projectile had struck the vessel. The crew safely abandoned it and were recovered by a tug. At the latest cited update, the fire was not extinguished, the vessel was adrift, and no environmental impact was reported. Vessel identity, projectile source, responsibility, and casualty status were not established in the UKMTO notice.

The tanker reported being struck by an unknown projectile 19 nautical miles east of Khasab, causing minor structural damage to its port side. UKMTO reported that all crew were safe and accounted for, no environmental impact had occurred, and the vessel was continuing to its next port while authorities investigated. Vessel identity, cargo, projectile source, and responsibility were not established in the notice.

Military authorities reported that a tanker was struck by a missile 13 nautical miles southeast of Limah while transiting outbound on the southern route. UKMTO reported that authorities were investigating. The warning did not state the incident time, vessel identity, damage extent, casualty status, environmental impact, missile source, or responsibility. Archived UKMTO Warnings 086-26 and 087-26 contain the same incident details, so they are represented as one map event rather than assumed to be separate attacks.

UKMTO reported that a container ship sustained damage to the rear of the vessel and caught fire approximately 9 nautical miles east of Oman while transiting the Strait of Hormuz. US Central Command separately identified the vessel as the Cyprus-flagged container ship GFS Galaxy and said it was attacked by Iran's IRGC, causing significant engine-room damage and a fire that left the vessel unable to continue its voyage. The 24-member crew abandoned ship in a lifeboat and were rescued; one crew member, an Indian marine engineer, was reported missing and was later confirmed dead. The US military carried out retaliatory strikes against Iran in the following days. No environmental impact was reported in the cited advisories.

Military authorities reported that an unknown uncrewed aerial vehicle struck a tanker transiting the Strait of Hormuz. UKMTO reported minor structural damage, no casualties or environmental impact, and that the vessel continued to its next port. JMIC placed the incident approximately six nautical miles east of the Musandam Peninsula. The vessel identity, tanker class, cargo, UAV source, and responsibility were not established.

A third party reported that an unidentified projectile struck a tanker transiting the Strait of Hormuz and that the vessel was believed to have structural damage. No casualties or environmental impact were reported. JMIC later described the vessel as a VLCC and placed the incident approximately 16 nautical miles east of Khor Fakkan. The vessel identity, cargo, projectile source, and responsibility were not established in the UKMTO warning.

UKMTO/JMIC reported that a tanker travelling southbound was struck by an unknown projectile on the port side engine room approximately 8 nautical miles east of Limah, Oman, causing a fire. The advisory did not identify the vessel, vessel class, cargo, casualties, environmental impact, projectile source, or responsibility.

Yemen's Houthis said they targeted crude-oil supply and transport sites linking eastern Saudi Arabia to the Red Sea export hub of Yanbu, including Petroline, the 1,200km pipeline carrying crude from the kingdom's eastern fields — marking the first time the group has targeted oil infrastructure in eastern Saudi Arabia since 2019. With Strait of Hormuz disruptions pushing Saudi Arabia to move up to 5 million barrels a day through this route (up from about 1 million previously), Saudi authorities said they reserve the right to respond but had not released the extent of any damage at the time reported.

Iranian cruise missiles struck the ADNOC L&S-operated VLCCs Al Bahyah and Mombasa B while they transited the Strait of Hormuz, causing significant damage. UAE authorities reported that one Indian seafarer was killed and eight people were injured, four seriously. ADNOC L&S confirmed the two projectile attacks; this grouped record does not imply that both vessels suffered identical damage or casualties.

The Abu Dhabi National Oil Company (ADNOC) said two of its vessels were attacked while transiting the Strait of Hormuz, the UAE's WAM state news agency reported. ADNOC said there were no injuries and the situation was brought under control. The UAE's Foreign Ministry condemned the attack. Neither ADNOC nor WAM identified an attacker in the cited reporting, and vessel names have not been published; this record will be updated as more detail becomes available.

The Abu Dhabi National Oil Company (ADNOC) said one of its vessels was attacked while transiting the Strait of Hormuz on Friday local time, according to a CNN update citing the UAE's WAM state news agency. ADNOC said the situation was brought under control and no injuries were reported. CNN described this as the third reported attack on ADNOC tankers in under a week. The reviewed update did not identify the vessel, attack method, attacker, damage or precise location. This is recorded separately from the two-vessel incident reported the previous day because the update explicitly described a Friday attack; the records should be reconciled if ADNOC or maritime authorities later clarify that it referred to an earlier event.
