The attack happened early on Saturday.
The pirates were on board five speedboats. They tried to hijack the Iranian oil vessel but were forced to flee following a heavy exchange of fire with the Navy’s 78th flotilla of warships.
Iranian Navy Commander Rear Admiral Shahram Irani said the flotilla including Alborz Destroyer was escorting the Iranian oil tanker when the incident happened.
He described the attack as “maritime terrorism”.
“With the timely action of the army marines, the two tankers safely passed through the Gulf of Aden, and now our country’s ships and those of other countries are sailing through this area safely, and so far no specific case has been reported there,” he added.
Iran has deployed warships to international waters to protect naval routes and maintain security for cargo ships.
