BBC Verify collated incident reports published by the UKMTO on its website and created a timeline based on the first date cited in each report. The analysis shows that the 12 weekly attacks represent the highest number of strikes reported since the US-Israeli war with Iran began.
The types of attacks varied widely. Some vessels reported being struck by airborne drones, others by small uncrewed surface vessels (USVs) or missiles. For example, the tanker ATLANTIC TIGER was reportedly struck by a USV in the Gulf of Oman, while the BAHRA was hit by a missile. The crude tanker OCEAN SEVEN reported being struck by two missiles. The product tanker LANCELOT was struck by an airborne drone, causing damage. The crude tanker STONEWELL was struck by a USV. The support vessel OCEAN BREEZE reported an explosion alongside it. The crude tanker PROGRESS was hit by a missile. The oil tanker PACIFIC GOLD reported being struck by a USV. The BW MAERSK, a product tanker, was struck by an airborne drone, forcing repairs in port.
UKMTO data shows the attacks clustered around the Strait of Hormuz, between Iran and Oman, near the Musandam Peninsula, and in the southern Gulf and Gulf of Oman.
Oil exports through the Strait of Hormuz, a chokepoint through which about a fifth of the world's petroleum passes, have been disrupted. The recovery in oil shipments seen last month has slowed as the number of attacks has risen, according to industry data.
