What happened

US Marines from the 31st Marine Expeditionary Unit boarded the Iranian-flagged commercial oil tanker M/T Celestial Sea in the Gulf of Oman. CENTCOM said the vessel was suspected of attempting to violate the US blockade by sailing toward an Iranian port. US forces searched the tanker, directed its crew to alter course and then released it. The official account did not publish the precise position, cargo details, search findings or boarding duration; no damage, casualties or pollution were reported.
