Earlier, Gibraltar decided to release the detained Iranian tanker Grace 1, which was later renamed Adrian Darya 1. The corresponding decision was made due to the fact that the authorities received official written assurances from the Iranian government that the ship would not unload its cargo in Syria.

Later, Iran’s ambassador to the UK, Hamid Baedinejad, reported that the tanker Adrian Darya 1 sold oil to a private company and did not violate Tehran’s obligations.
