Two very large crude carriers, the Liberia-flagged Senegal Prosperity and Saudi-flagged Sidr, were attacked by rockets while transiting an Oman route south of the Strait of Hormuz on September 1. The incidents occurred at 1:30 a.m. Iran time, or 7:00 a.m. Korea time, according to the UK Maritime Trade Organisation (UKMTO) and maritime firms. Vanguard-Tech said three rockets struck Senegal Prosperity near Oman’s coast, hitting its port side, engine room and ballast tank. Marisks said Sidr was attacked by multiple rockets eight minutes earlier. Each vessel had loaded 2 million barrels of crude at Saudi Arabia’s Jubail port days before the attacks. Senegal Prosperity is owned and operated by Seoul-headquartered Sinokor Maritime, while Sidr is owned and operated by Bahri, Saudi Arabia’s state-owned shipping firm. The attacks followed an August 30 U.S. strike on Larak Island and Iran’s August 31 attack on two Jordanian military bases housing U.S. forces. No group claimed responsibility, although the source says Iran has repeatedly targeted energy transport vessels since the war began. The route was newly established by the U.S. and described as fully open and under U.S. military protection, but Marisks said the near-simultaneous attacks weakened assumptions that it was secure or low risk. The incidents also followed President Donald Trump’s August 25 announcement that U.S. Navy SEALs and supporting forces had removed all mines in the strait, while U.S. Central Command confirmed the clearance of Iranian-laid mines from internationally recognized shipping lanes. Ships have since transited at night with transponders turned off, yet more than 12 vessels were attacked in August, including the Kuwaiti tanker Burgan on August 29. Trump said on August 31 that the strait was in very good shape, remained open and supported an average of 30 ships each night, but Windward data showed only 10 ships entered or exited the Gulf on August 30. Iranian President Masoud Pezeshkian said on September 1 that Iran would immediately take reciprocal measures if the U.S. resumed its commitments under the June agreement.
