On 13 June two subsequent blasts in the Straits of Hormuz damaged a Japanese and a Norwegian tanker, and were blamed on Iran by the U.S. military. A video was released which, according to the United States, shows an Iranian vessel removing an unexploded limpet mine from the starboard side of the Japanese vessel, several meters forward of the damaged area. The implications of an Iranian attack are disputed by the owner of the Japanese vessel and the Japanese government. The mines seemed to have been placed many feet above the waterline. The vessel's crew reported an unknown object flying towards them, then an explosion and a breach in the vessel. After this, the crew witnessed a second shot.
