The State Department said on Friday that the US government had seized the vessel and its cargo of 980,000 barrels of crude oil, alleging it was transporting Iranian oil to China in violation of Washington’s sanctions against Tehran.
It further claimed that the US government obtained a warrant earlier this year for its seizure.
On April 19, around the time of the seizure, the vessel’s owner, Suez Rajan Ltd, pleaded guilty to sanctions violations and was fined $2.5 million.
Subsequently, the Greek vessel’s operator, Empire Navigation, agreed to cooperate with US authorities and ordered the ship, located in Southeast Asia at the time, to take its load of oil to the United States.
The commander of the Islamic Revolution Guards Corps (IRGC) Navy warned on July 20 that any oil company unloading hundreds of thousands of barrels of seized Iranian oil sitting in a Greek tanker off the coast of Texas would be held accountable.
