The United States has blacklisted the Iranian tanker Adrian Darya, saying it had “reliable information” it was transporting oil to Syria in defiance of wide-ranging sanctions on the regime of Bashar al-Assad. Previously known as Grace 1, the vessel was seized in July by British Royal Marines and held in Gibraltar for six weeks on suspicion it was delivering oil for Tehran’s ally Damascus. The British territory released the ship — despite US protests — after it said it had received written assurances from Iran that the vessel would not head for countries under European Union sanctions.
