The tweet included a picture of Adrian Darya 1 by the Syrian Baniyas Port and Refinery - where British authorities believed it was heading when it stopped the tanker off the coast of Gibraltar in July.
Gibraltar security forces aided by British Royal Marines intercepted the Iranian supertanker, then called Grace 1, off the coast of the British overseas territory on July 4.
Authorites held the tanker on suspicion it was shipping its 2.1 million barrels of oil to Syria in breach of European Union sanctions.
Iran reacted with fury to the seizure, saying it was an act of "piracy". A Gibraltar court ordered its release in mid-August against US objections.
