US President Donald Trump on Sunday said the ​US Navy would immediately start blockading the Strait of Hormuz, and would also interdict ⁠every vessel in international waters that had ​paid a toll to ​Iran.

Trump ‌made his remarks ⁠in ​a Truth Social post hours after US-Iran peace talks ended without a deal.

Trump said the meeting "went ‌well, most points were agreed," but ‌added the two sides had not agreed on Iran's nuclear programme.

"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," said Trump.

"I have also 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," he said.
