The US has intercepted an Iranian ship entering the Gulf as part of its naval blockade, US President Donald Trump has said. Trump wrote on his Truth Social platform that the ship was seized by the US Navy after failing to respond to a warning to stop. In response, Iran claimed it was a violation of the ceasefire and vowed to retaliate for what they termed an 'act of armed piracy.' This incident marks the first ship seizure by the US since the blockade of Iranian ports began, escalating the ongoing tensions in the region. The situation continues to develop, and further information will emerge as both nations respond to this incident.
