The U.S. military intercepted three Iranian-flagged tankers—Deep Sea, Sevin and Dorena—in Asian waters, diverting them from positions near India, Malaysia and Sri Lanka, shipping and security sources said. The interception comes amid a U.S. blockade of Iranian maritime traffic, a response to Iran's firing on vessels attempting to exit the Gulf via the Strait of Hormuz. The closure of the strait has disrupted a fifth of the world's oil and gas supplies, contributing to a global energy crisis. Sevin, with a maximum capacity of 1 million barrels, was carrying 65% of its load when intercepted. Dorena was fully loaded with 2 million barrels of crude. U.S. Central Command reported that since the blockade began, U.S. forces had directed 29 vessels to turn around or return to port. The U.S. Central Command noted that Dorena had been under the escort of a U.S. Navy destroyer in the Indian Ocean after attempting to violate the blockade. A maritime security source said the U.S. military was targeting Iranian ships away from the Strait of Hormuz to avoid floating mines during operations. U.S. forces may have intercepted the Iranian-flagged Derya tanker, shipping sources said. The vessel failed to discharge its cargo of Iranian oil in India before a U.S. waiver on Iranian crude purchases expired on Sunday. That vessel was last seen off India's western coast on Friday, according to MarineTraffic data. The U.S. military has not listed all the ships it has intercepted and did not immediately respond to requests for comment about the Deyra and the Deep Sea.
