The vessel, the GFS Pride, caught fire after the strike and sank. Singapore's maritime authority called the attack "unprovoked, unjustifiable and a breach of international law." Iran's Revolutionary Guard claimed the ship hit a naval mine, a version reported by state news agency Tasnim. But maritime security firm Marisks said there is no independent evidence of a mine, describing Tehran's account as "consistent with an ongoing psychological operations campaign aimed at generating fear, increasing uncertainty and discouraging commercial shipping in Hormuz."
Iran has escalated strikes on commercial ships in recent weeks as it tries to choke off a rebound in crude oil exports through the strait. The United Kingdom Maritime Trade Operations Centre has recorded more than 20 attacks this month in the Strait of Hormuz, the Persian Gulf and the Gulf of Oman, mostly involving oil tankers. The International Maritime Organization reports two sailors missing and 12 injured from the attacks.
Crude oil exports through Hormuz hit prewar levels in September after the U.S. military began guiding tankers through the strait, but shipments have since pulled back. Data from Kpler shows that crude exports through Hormuz averaged 8.5 million barrels per day in the week ended Oct. 12, nearly 40% below normal prewar levels. Regional shipments, including pipeline flows, stood at 14 million barrels per day, about 20% below prewar levels. Daily flows remain volatile, with only 3 million barrels transiting Hormuz on Monday compared with 6 million on Friday.
