 In the afternoon of June 4th, the fast boats of the Iranian Revolutionary Guard Corps tried to capture a merchant ship moving in the strait of Hormuz. The US Navy's fifth fleet issued a statement about this. The statement said that the US and British navies in the region responded to the merchant ship's call for help. The destroyer USS McFall belonging to the US Navy as well as the frigate HMS Lancaster belonging to the British Royal Navy present in the region responded to the merchant ship's request for assistance. A British frigate, a helicopter and the USS McFall destroyer sent a maritime patrol plane to the location of the ship. After intervention to help the ship, SEPA edge boats left the area.
