A U.S. ship carrying cargo was said to have been seized by Iranian forces, but U.S. Navy officials denied the report, which came from the official Twitter feed of Saudi Arabian al-Arabiya television station. The station reported that Iranian forces took a U.S. ship that had about 34 American sailors onboard. They have reportedly taken the ship to the port at Bandar Abbas.

Details on the reported U.S. ship seizure

The Saudi TV network also reported that Iranian forces fired on the U.S. ship, which would have probably resulted in a sudden escalation of violence in the Persian Gulf if the report had been true. Not long after the first report appeared, officials with the U.S. Navy denied it

Al-Arabiya did not say where it received the information. According to the BBC, Fars, “Iran’s semi-official” news agency, reported that Iranian forces detained the U.S. ship for trespassing on Iranian waters.

Shortly after these reports, Reuters reported on its Top News Twitter feed that Iranian forces boarded the MV Maersk Tigris in the Persian Gulf. The news agency cited the Pentagon. The ship is flagged from Marshall Island and not the U.S.

Some were speculating that Saudi Arabia may have been seeking to derail the Iran nuclear deal. It’s no secret that Saudi Arabian officials oppose the deal between Iran and the U.S.
