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 responded by stating that this action violates the ceasefire and threatened retaliation against what it termed an 'act of armed piracy.' This incident marks the first ship to be seized by the US since the blockade against Iranian ports began. Here’s what we know so far about this unfolding situation.
