An oil tanker caught fire after being struck by an unidentified projectile in the Strait of Hormuz, the United Kingdom Maritime Trade Organization said. Local authorities reported that the incident occurred Tuesday in the waterway between Oman and Iran; the crew was safe and no environmental damage was reported. Iran has not claimed responsibility. The attack comes as the strait remains effectively closed to normal commercial traffic following the onset of a joint U.S. and Israeli assault on Iran earlier this year. Roughly one-fifth of global oil and liquefied natural gas shipments moved through the waterway before the conflict. Five confirmed crossings were recorded Tuesday, down from seven a day earlier and more than 130 vessels a day before the war, according to Kpler, with all five using Iran's designated unilateral route. U.S. allies have questioned claims that mines have been fully cleared, while Iran and Oman are working toward an arrangement that could establish a temporary shipping corridor and support mine clearance. Qatar's Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani held talks in Iran on a proposed phased framework, while Pakistan said Field Marsh Asim Munir's visit was aimed at reviving an expired interim ceasefire. The disruption has lifted oil prices and raised concerns about renewed inflation and tighter central-bank policy. Markets and shipping operators will monitor further attacks, mine-clearance and escort activity, sanctions, ceasefire diplomacy and shipping data for signs of whether traffic can normalize by September 30.
