The US has intercepted an Iranian-flagged cargo ship in the Gulf as part of its naval blockade, Donald Trump has said, BBC reported. 

The US president wrote on his Truth Social platform that the Touska was seized by the US Navy after failing to respond to a warning to stop. Iran said it was a violation of the ceasefire and it would retaliate soon for the "act of armed piracy". 

The announcement came after the White House confirmed US Vice-President JD Vance would lead another delegation for a second round of talks on ending the war with Iran in Pakistan.
