US Launches Fresh Strikes On Iran After Strait Of Hormuz Attacks

The U.S. military said it had launched additional strikes on Iran aimed at weakening Tehran's ability to threaten commercial shipping through the Strait of Hormuz, one day after three cargo ships were attacked while transiting the strategic waterway.

In a post on X, U.S. Central Command said its forces had begun "conducting additional strikes against Iran to further degrade their ability to threaten freedom of navigation in the Strait of Hormuz."

"The United States is holding Iran accountable for recent unjustified aggression against commercial shipping and civilian crews freely navigating a vital international waterway," CENTCOM said.

Trump said the strikes were retaliation for the attacks on commercial vessels, warning Tehran against further escalation.

"This is in retribution for yesterday's bombing of ships by Iran. If it happens again, it will get much worse!" Trump wrote on Truth Social.

Trump Says Iran Accord Is 'Over'

Speaking before a NATO summit in Turkey, Trump said an interim memorandum of understanding signed on June 17 to end hostilities had effectively collapsed.

"To me, I think it's over. I don't want to deal with them," Trump said, later adding, "If we make a deal with Iran I'm not sure that will stick."

Iranian Foreign Minister Abbas Araghchi responded on X, saying Iran would not answer "vulgarity with vulgarity, but with action: fearlessly and with great valor."

Former Vice President Mike Pence also weighed in, urging Trump to "Finish the Job" by destroying Iran's nuclear and missile programs and restoring freedom of navigation through the Strait of Hormuz.
