What happened

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.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
