The tankers, sailing under the flags of Botswana and Angola, had intended to pass through the strait, the report said, but were forced to change course.President Donald Trump convened a Cabinet meeting in the situation room Saturday morning to discuss the Strait of Hormuz and the situation in Iran, according to two U.S. officials with knowledge of the meeting.He had earlier said that his administration was currently talking to Iran, and that talks were going “very well.”But Iranian President Masoud Pezeshkian said Sunday that Trump was seeking to deny Iran its “nuclear rights,” and that Iran was trying to end the war “with full dignity.””If a human being does not defend himself, he is dead,” he said. “They attacked us, and we defended.”Maritime authorities reported Saturday gunfire and a projectile strike involving Indian vessels in the strait. Iranian state media has confirmed that shots were fired near the two Indian ships to force them to turn back.Iran’s Islamic Revolutionary Guard Corps warned vessels against approaching the Strait of Hormuz, which it said would be considered “cooperation with the enemy,” adding that “any violating vessels would be targeted.”The Trump administration said its blockade of Iranian ports remains in force, with more than 20 ships turned back since Monday.Following a summit of 51 countries that was co-chaired by France and the U.K. on Friday, French President Emmanuel Macron and British Prime Minister Keir Starmer “called for the unconditional, unrestricted, and immediate re-opening of the Strait of Hormuz.” They also announced a joint neutral mission to provide reassurance to merchant vessels in the region.
