The United States on Friday threatened sanctions against "anyone providing support to the Adrian Darya 1," the Iranian oil tanker that has amplified tensions between Tehran and the West, Deutsche Welle reports.
Previously known as Grace 1, the ship has been bouncing around the Mediterranean after being held for six weeks by Gibraltar on suspicion that its cargo was bound for Syria.
The US Treasury Department declared that the vessel is now "blocked property" under an executive order that targets terrorists and those providing support to terrorism.
