Iranian state news outlets released dramatic footage of their naval forces warning and forcing a US warship to stay away from the Strait of Hormuz, but the US has not confirmed the incident.
US President Trump announced the US Navy will blockade the strait, amid Iran's plans to selectively allow some vessels upon payment of a toll reportedly around $2 million per ship.
The confrontation, as seen in the 64-second video, began with a person from the Islamic Revolutionary Guard Corps telling the US Navy Warship 121 to alter course and go back to the Indian Ocean immediately.
The US has claimed to have carried out a mine-clearing operation in the global oil waterway, while Iran has effectively blocked the strait for weeks, resulting in unprecedented supply disruption.
