Xinhua News Agency, April 27, the Iranian army issued a statement on the 27th local time, saying that it had detained a US ship flying the Marshall Islands. The statement said that the act of an unidentified vessel violated international law because of an accident between an unidentified ship and an Iranian ship in the northern Indian Ocean, resulting in two deaths and several injuries on board an Iranian ship. Immediately after the Iranian ship sent a request to the Maritime Surveillance and Rescue Center, the Iranian navy began to intercept and identify the unknown ship. During the interception of Iranian naval destroyers, the automatic global positioning (GPS) transmission system of unknown ships was shut down and frequently changed course. With the permission of the Iranian judicial authorities, the navy dispatched helicopters to seize the ship and transport it to Iranian territorial waters. The statement pointed out that the above-mentioned unidentified vessels belonged to the United States and sailed under the flag of the Marshall Islands.
