Iran's Revolutionary Guards "forcibly seized" a commercial ship in international waters in the Gulf on Thursday and the vessel was possibly involved in smuggling, a U.S. Navy spokesperson said.
The U.S. Navy had monitored the situation and decided not to make any further response, U.S. 5th Fleet spokesperson Commander Tim Hawkins said.
British maritime security company Ambrey said it was aware of an attempted seizure by Iranian forces of a small Tanzanian flagged tanker, around 59 nautical miles northeast of the Saudi Arabian port city of Dammam.
