Series of Projectile Strikes on Unnamed Vessels in Strait of Hormuz, 10–14 September

Four separate strikes on unnamed commercial vessels were recorded in the Strait of Hormuz between September 10 and 14, as Iranian maritime interdiction activity continued at elevated intensity.

On September 10 at 1910 UTC, a tanker master observed a vessel on fire approximately six nautical miles ahead. At 1949 UTC, the same master reported both his vessel and a second unidentified ship had each been struck by two unknown projectiles, heard on VHF Channel 16 and observed visually. UKMTO conducted a see-and-avoid search but located no vessel reporting to it in the area. No casualties or environmental impact were confirmed.

On the night of September 12–13, a tanker with identity withheld issued a distress call at 2330 UTC after being struck near Limah, Oman, while transiting southbound. A fire broke out in the engine room. Omani Coast Guard vessels assisted with crew evacuation; no casualties were reported. A SAR satellite pass approximately 15 hours after the strike detected a dark, non-AIS-transmitting tanker on the reported attack corridor with an oil-spill signature.

On September 13, Iran's state broadcaster IRIB separately reported that an Iranian-flagged commercial vessel was struck near Qeshm Island, killing one crew member and injuring four. The Qeshm governor blamed a "terrorist enemy." The vessel's name and type were not disclosed. Whether the strike originated from a U.S., third-party, or accidental source has not been confirmed.

On September 14, UKMTO issued a further advisory confirming a vessel was struck by an unknown projectile in the strait with no damage or environmental impact reported.

JMIC rates the Hormuz threat level as severe. UKMTO has advised all vessels to transit with caution and report suspicious activity.
