Washington:The US has blacklisted the Adrian Darya-1, an Iranian tanker, which was released by Gibraltar earlier this month after it was detained in July, over claims that it was being used to ship oil to Syria.
According to the information, the ship, with its cargo of 2.1 million barrels of oil, and crew of 29 from India, Russia, Latvia and the Philippines, was seized with the help of British marines on July 4, after the government of Gibraltar, a UK territory, suggested it was heading for Syria in breach of European Union sanctions.
Previously known as Grace 1, the Adrian Darya-1 was released on August 18 after Iran gave assurances that it would not discharge its cargo in Syria.
In a statement on Friday night, the US Treasury said that the Adrian Darya 1 was being used to transport 2.1 million barrels of Iranian crude oil for the benefit of Iran's Islamic Revolutionary Guard Corps (IRGC) - a branch of the country's armed forces that the US has designated a terrorist organisation.
It insisted that ships like Adrian Darya 1 were being used to sell oil illicitly to fund Iran's 'malign activities and propagate terrorism'.
US Secretary of State Mike Pompeo added in a tweet that Washington had 'reliable information' the vessel was on course to Tartus, a major Syrian port city which is also home to a Russian naval base.
