An Iranian supertanker with $130 million worth of light crude oil that the U.S. suspects is tied to a sanctioned organization left Gibraltar and was heading east into the Mediterranean Sea on Monday, with its next destination reported to be Greece. The Iran-flagged Adrian Darya 1, previously named Grace 1, set course for Kalamata, Greece, with an estimated arrival on Aug. 25, according to ship tracking service MarineTraffic. The vessel left Gibraltar late Sunday after having been detained for a month in the British overseas territory for allegedly attempting to breach European Union sanctions on Syria.
