Iran tanker in limbo off Gibraltar as US issues warrant

A last-minute US warrant to seize an Iranian oil tanker preparing to leave Gibraltar after weeks of detention cast doubt over its departure on Saturday, prolonging a diplomatic spat between Tehran, London and Washington. The US Justice Department alleged the ship was part of a scheme "to unlawfully access the US financial system to support illicit shipments to Syria from Iran by the Islamic Revolutionary Guard Corps," which Washington has designated a foreign terrorist organisation. There was no comment from Britain or Gibraltar, its overseas territory.
