The US has intercepted an Iranian ship entering the Gulf as part of its naval blockade, US President Donald Trump has stated. Trump posted 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 has labeled the seizure as a violation of the ceasefire, threatening retaliation for what they call an 'act of armed piracy'. This incident marks the first ship to be seized by the US since its blockade of Iranian ports began. Below is what we know so far about the incident.
