(CNN)The United States has unsealed a warrant for the seizure of an Iranian oil tanker anchored off the coast of Gibraltar. It is the latest twist involving the vessel at the center of a standoff between Tehran and the West.
The warrant comes just a day after a judge in Gibraltar said the Grace 1 supertanker — which is reportedly carrying 2.1 million barrels of oil — was free to set sail.
The tanker was seized by authorities while passing through Gibraltar’s waters in early July on suspicion of taking oil to Syria — which would have been in breach of European Union sanctions. Gibraltar is a British territory on Spain’s southern coast.
