The U.S. has intercepted an Iranian ship entering the Gulf as part of its naval blockade, U.S. President Donald Trump announced. In a post on his Truth Social platform, Trump indicated that the ship was seized by the U.S. Navy after it failed to respond to a warning to stop. Iran has retaliated by labeling the seizure a violation of ceasefire and has pledged to respond soon for what they describe as an 'act of armed piracy.' This incident marks the first seizure since the U.S. initiated its blockade of Iranian ports, raising tensions in an already volatile region.
