Iran’s top diplomat said a US attempt at “piracy” had failed after a Gibraltar court on Thursday ordered the release of a tanker carrying Iranian oil despite a US detention request. A supreme court judge in Gibraltar ruled in favour of releasing the Grace 1 supertanker which had been seized in waters off the British territory on July 4 on suspicion of breaching EU sanctions on Syria. “Having failed to accomplish its objectives through its #EconomicTerrorism — including depriving cancer patients of medicine — the US attempted to abuse the legal system to steal our property on the high seas,” Iranian Foreign Minister Mohammad Javad Zarif tweeted.
