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. Iran stated that this act represents a violation of the ceasefire and announced intentions to retaliate for what it described as an 'act of armed piracy.' This incident stands as the first instance of a ship being seized since the onset of the US blockade on Iranian ports. The escalating exchange underscores the fraught dynamics in the region as both sides prepare for potential consequences of this military maneuver.
