President Donald Trump said that the U.S. will “immediately” begin a blockade of the Strait of Hormuz, following the failure of peace negotiations between the U.S. and Iran.
“[T]he meeting went well, most points were agreed to, but the only point that really mattered, NUCLEAR, was not,” Trump wrote on his social media platform Sunday. “Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all ships trying to enter, or leave, the Strait of Hormuz.”
The president did not provide specifics in his social media posts. ABC News has reached out to the White House for comment.

Trump’s statement comes after Vice President JD Vance, leading a U.S. delegation for high-stakes talks with Iran, said Saturday that the two sides had not reached a deal despite negotiations lasting some 21 hours in Islamabad, Pakistan. Though he declined to provide specifics about why the negotiations deteriorated, Vance said it was in part because the U.S. did not see the “fundamental commitment” from the Iranians not to develop a nuclear weapon in the long term.

Calling Iran’s blockage of the Strait of Hormuz “WORLD EXTORTION,” the president also said that he had “instructed our Navy to seek and interdict every vessel in International Waters that has paid a toll to Iran. No one who pays an illegal toll will have safe passage on the high seas.”
“We will also begin destroying the mines the Iranians laid in the Straits,” Trump wrote. “Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL!”
“The Blockade will begin shortly. Other Countries will be involved with this Blockade. Iran will not be allowed to profit off this Illegal Act of EXTORTION,” the president wrote. “They want money and, more importantly, they want Nuclear. Additionally and, at an appropriate moment, we are fully ‘LOCKED AND LOADED,’ and our Military will finish up the little that is left of Iran!”
