A tanker was struck by an unidentified projectile about 19 nautical miles northeast of Lima, Oman, near the Strait of Hormuz, at 13:38 UTC on Tuesday, November 10, the United Kingdom Maritime Trade Operations (UKMTO) centre said in Warning 201-26. The vessel's master reported that all crew members were safe and there was no environmental impact, and a damage assessment was planned for first light on Wednesday.

Separately, ADNOC Logistics & Services confirmed that one of its vessels sustained damage in an attack in the United Arab Emirates' territorial waters, in the Arabian Gulf, on the afternoon of November 10. In a statement carried by the UAE's state news agency WAM, the company said response operations by the relevant teams were ongoing, and that further updates would be provided as more information became available.

ADNOC did not name the vessel, say what type of ship it was, describe the extent of the damage, or say whether any crew members were injured. It was also not immediately clear whether the ADNOC incident and the tanker strike reported by UKMTO were connected, or were two separate attacks, gCaptain reported.

Iran's Revolutionary Guards claim tanker explosions in the strait

Iran's Islamic Revolutionary Guard Corps (IRGC) Navy said in a statement on Tuesday that two oil tankers attempting to use what it called an unauthorised route through the Strait of Hormuz had suffered explosions and caught fire, the Iranian outlet Press TV reported. The Guards said one vessel, described as a supertanker, hit a naval mine, and that a second tanker, which it said was operating under the protection of US military aircraft, caught fire while trying to cross the waterway secretly. The shipping publication TradeWinds reported that the IRGC had claimed three tanker casualties in the strait on the same day. These Iranian claims are attributed to the IRGC and have not been independently verified.

The maritime intelligence firm Vanguard Tech identified the tanker in the UKMTO report as the Sea 1, a UAE-controlled product tanker of 74,100 deadweight tonnes built in 2006, TradeWinds reported. UKMTO itself did not identify the tanker and did not establish where the projectile came from.

There had already been another reported strike a day earlier: the maritime security firm Ambrey reported an incident late on Monday about 17 nautical miles northeast of Khasab, Oman, in which an unidentified merchant vessel outbound through the waterway was struck on its port side by a projectile, TradeWinds said.

A strait under a 'severe' threat warning

The latest strikes come days after the Joint Maritime Information Center (JMIC) kept its threat level for the Strait of Hormuz at SEVERE in its November 8 advisory, warning that further deliberate attacks were highly likely. JMIC had reported five attacks off Oman's Musandam coast between November 1 and November 5, followed by more incidents on November 7, when a tanker caught fire about eight nautical miles northwest of Khasab and its crew was evacuated, and a second outbound tanker was struck by a projectile. The Strait of Hormuz carried roughly a fifth of the world's traded oil and gas before the war that began on February 28, 2026.

Crews on tankers crossing the strait include large numbers of Indian seafarers, among them Punjabis working in the Gulf shipping trade. In Tuesday's UKMTO incident the master reported the whole crew safe; ADNOC released no information about the crew of its damaged vessel.
