What happened

US Marines from the 31st Marine Expeditionary Unit boarded M/V Blue Star III in the Arabian Sea after CENTCOM said the commercial vessel was suspected of attempting to transit to Iran in violation of the US blockade. US forces released the vessel after a search confirmed that its voyage would not include an Iranian port call. The official account did not publish the vessel's flag, type, precise position, cargo details or boarding duration; no damage, casualties or pollution were reported.

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.
