Iranian tanker Grace1 leaves Gibraltar

The Iranian tanker Grace1 caught in a standoff between Tehran and the West left Gibraltar on Sunday night, shipping data showed, hours after the British territory rejected a U.S. request to detain the vessel further.

The Grace 1, renamed the Adrian Darya 1, left anchorage off Gibraltar around 11 p.m. (2100 GMT), Refinitiv shipping data showed. Its destination was not immediately clear, Reuters reported.

Iran’s ambassador to Britain, Hamid Baeidinejad, had written on Twitter earlier that the vessel was expected to leave on Sunday night, adding that two engineering teams had been flown to Gibraltar.

The tanker’s detention ended last week, but a federal court in Washington on Friday issued a warrant for the seizure of the tanker, the oil it carries and nearly $1 million.

Gibraltar said it could not comply with that request because it was bound by EU law.
