Iran's port authority said Tuesday it has been in contact with British authorities as part of efforts to secure the release of a tanker seized off Gibraltar.
Gibraltar -- a British overseas territory -- seized the Grace 1 supertanker on July 4 with the help of British Royal Marines on suspicion it was shipping oil to Syria in violation of EU sanctions.
A court in Gibraltar is to decide the fate of the ship on Thursday, when an order for its detention lapses.
The deputy head of Iran's port authority, Jalil Eslami, said in a report by state news agency IRNA that Britain had shown an interest in overcoming the problem and documents had been exchanged.
"Efforts from Iran and the port organisation have been made for the release of this ship," he was quoted as saying.
"I hope this problem will be resolved in the near future and that the ship can continue its movement with the flag of the Islamic Republic of Iran."
