U.S. Central Command said a short time later that its forces began a third round of strikes against Iran.
“The United States is imposing a heavy cost by continuing to degrade Iran’s ability to attack civilian mariners and commercial ships freely transiting the strait,” the military said.
A Cyprus-flagged container ship struck by Iran suffered “significant engineroom damage” and a civilian crew member is missing, U.S. Central Command said.
Senior U.S. officials had previously said in Washington that negotiations to further cement last month's deal to end the war will be unable to progress without the strait being secure — and had even said they expected Iran to offer public statements to that effect.
Instead, the Revolutionary Guards Corps stated in an online post on Saturday that Iran launched warning shots at a “violating ship.” Iran further reported that the strait would now remain closed until further notice.
Those announcements followed Iran and Oman’s foreign ministers meeting on Saturday to discuss the strait that lies between them, after days of Iranian attacks on ships and U.S. retaliation that dealt a blow to the interim deal to end the war.
Iran’s new supreme leader, still unseen since the war began, also vowed in his first statement since the funeral of his father, Ayatollah Ali Khamenei that Iranians would avenge his killing in the war’s opening strikes on Feb. 28.
Such revenge “is the will of our nation and must certainly be carried out,” Supreme Leader Mojtaba Khamenei said in a statement carried on state television, hours after President Donald Trump threatened more missile attacks.
Oman said it and Iran agreed to keep talking about the Strait of Hormuz “at the technical and political levels,” a day after the United States called on Iran to publicly say the crucial waterway is open and ships won’t be attacked.
