A commercial tanker was hit by an unidentified projectile off the coast of Oman on Monday evening, causing a fire on board. No casualties or environmental damage were reported, according to the United Kingdom Maritime Trade Operations (UKMTO). The incident occurred at 21:19 UTC while the vessel was sailing south, approximately eight nautical miles east of Lima, Oman.

The UKMTO said the projectile struck the port side. Meanwhile, US officials, speaking to Axios, claimed that Iran’s Islamic Revolutionary Guard Corps fired at least two missiles at commercial ships transiting the Strait of Hormuz, damaging two vessels significantly but causing no injuries. The Wall Street Journal, citing a recording, reported that the IRGC had warned ships via marine radio that “our missiles and drones are ready to fire at you.” Bloomberg identified one of the vessels as a Qatari-owned LNG carrier, the Al Riqayat, which had loaded gas at Ras Laffan and was exiting the strait when hit. Iranian state television, without claiming responsibility, linked the attack to the ship’s disregard of warnings about designated transit routes.

The strait, a vital energy corridor, has seen heightened tensions. Iran has insisted that vessels obtain permission and use routes it approves, while some ships have opted for a path closer to Oman’s coast, challenging Tehran’s control. A temporary US-Iran understanding on navigation was reached in June, but incidents have persisted. On Monday, President Trump said the US would either reach a deal with Iran or “finish the job.” Oman, the UK, and France recently announced cooperation to secure Omani waters and support freedom of navigation.

No group or country has officially claimed responsibility. British maritime authorities have not commented on the projectile’s origin. The UKMTO has advised ships to exercise caution and report suspicious activity. The incident remains under investigation.
