Gibraltar releases seized Iranian tanker despite US attempts to block

Gibraltar has released a seized Iranian oil tanker, despite a last-minute attempt by the US to block it. The Grace 1 was seized by British Royal Marines last month on suspicion it was violating EU sanctions by carrying oil to Syria. Soon after, Iran captured a British-flagged tanker, creating a confrontation between Iran and the West. The Grace 1 has not moved yet, but Gibraltar said it had received assurances the tanker would not sail to Syria. Dani Isdale reports.
