Iran seized a Marshall Islands-flagged oil tanker in the Gulf of Oman in international waters on Thursday, the US Navy said, the latest in a series of seizures and attacks on commercial vessels in Gulf waters since 2019.
The US Navy identified the vessel as the Advantage Sweet.
"Iran's continued harassment of vessels and interference with navigational rights in regional waters are a threat to maritime security and the global economy," the US Navy said, adding that Iran has in the past two years unlawfully seized at least five commercial vessels in the Middle East.
Since 2019 there have been a series of attacks on shipping in the strategic Gulf waters at times of tension between the United States and Iran.
Iran last November released two Greek-flagged tankers it had seized in the Gulf in May in response to the confiscation of oil by the United States from an Iranian-flagged tanker off the Greek coast.
