US Secretary of State Mike Pompeo says anyone who “touches,” supports or allows an Iranian tanker carrying crude oil to dock risks US sanctions.He told reporters Tuesday that if an Iranian supertanker that left Gibraltar on Sunday again heads to Syria, “we’ll take every action we can consistent with those sanctions to prevent that.” Greece said earlier in the day that it had not had a request from the Adrian Darya 1, the vessel at the center of a dispute between Iran and the United States, to dock at one of its ports, as Washington warned Greece against helping the vessel.The tanker, formerly called Grace 1, left Gibraltar on Sunday. Ship-tracking data on Tuesday showed the vessel was heading toward the Greek port of Kalamata on the southern coast of the Peloponnese and was scheduled to arrive next Monday. “We have made clear that anyone who touches it, anyone who supports it, anyone who allows a ship to dock is at risk of receiving sanctions from the United States,” Pompeo told reporters at the United Nations.He said that if the tanker’s oil was sold, the revenue would be used by elite units of Iran’s Revolutionary Guards. “We want to deny them the resources to continue their horrific terror campaign,” Pompeo said. The tanker is carrying about 2 million barrels of oil.“The vessel is cruising at low speed and there is still no formal announcement that it will arrive at Kalamata. The Merchant Marine Ministry is monitoring the matter along with Greece’s Foreign Ministry,” a Greek Shipping Ministry spokesman said.The ship, which is now sailing under an Iranian flag, was released from detention off Gibraltar after a five-week standoff over whether it was carrying Iranian oil to Syria in violation of European Union sanctions.Soon after the detention order was lifted, a US federal court ordered the seizure of the vessel on different grounds, but that petition was rejected by Gibraltar.Tehran said any US move to seize the vessel again would have “heavy consequences.” The United States in turn has also conveyed its “strong position” to the Greek government over the tanker.Washington wants the tanker detained on the grounds that it had links to Iran’s Revolutionary Guards, which it has designated a terrorist organization.The European Union, of which Greece is a member, bans oil sales to Syria and the United States has sanctions on Iranian oil sales.Impact on detained UK tanker?The fate of the Adrian Darya 1 could also have a bearing on that of a British-flagged tanker seized by Iran in the Strait of Hormuz leading into the Gulf two weeks after British Royal Marine commandos seized what was then known as the Grace 1.Speculation has mounted that the Stena Impero could be freed once the Adrian Darya 1 had set sail, although Iranian officials have denied any link between the two cases.Deputy Transport Minister Mohammad Rastad said the case of Stena Impero had been submitted to a court in the southern port city of Bandar Abbas, the semi-official news agency Tasnim reported, without giving a date when it would be heard.The handling of the Adrian Darya 1 will be a major foreign policy test for Greek Prime Minister Kyriakos Mitsotakis, a pro-Western conservative elected in July.Any efforts to assist the tanker could be construed as providing material support to a US-designated foreign terrorist organization, which has immigration and potential criminal consequences, a US State Department official said.A Greek diplomatic source cited by the state Athens News Agency said the country was in communication with the United States on the matter, but did not say what Greece would do.“(The US) position on the specific issue is known and has been communicated not only to Greece but other states and ports in the Mediterranean,” the source said.It is standard practice for a vessel to give 48 hours’ notice before docking at a port, Greek officials said.It was not clear where the ship might head if Greece refused it permission to dock.Cyprus, farther east, has bitter experience from seizing Iranian products destined for Syria. Munitions it confiscated exploded in 2011, causing the island’s worst peacetime disaster.
