TEHRAN, Iran — Iran’s navy says it has deployed two warships to the Gulf of Aden aimed at providing security to the country’s commercial shipping.

Piracy is a major concern in the Gulf of Aden, located between the Arabian Peninsula and Africa, and ships must pass through it when transiting the Suez Canal.

Iranian state TV said Monday that the destroyer Sahand carries surface-to-surface missiles, air defense systems and torpedoes, while the supply ship/replenishment oiler Kharg has a helicopter pad and serves in a logistical role.

The move comes amid a growing confrontation between Iran and the West.

Iran still holds a British-flagged tanker seized in July the Persian Gulf after a supertanker carrying Iranian oil was detained off Gibraltar, a British overseas territory.

The Iranian ship was released earlier this month, and Iran said Monday that its oil has been sold to an unnamed buyer.

The Adrian Darya, previously known as the Grace 1, carries 2.1 million barrels of crude, worth some $130 million.

Government spokesman Ali Rabiei made the announcement at a news conference on Monday in Tehran. He says the buyer of the oil will decide the ship’s ultimate destination.

The tanker was held for weeks off Gibraltar after being seized by authorities there on suspicion of violating EU sanctions on Syria.

The U.S. has a warrant in federal court to seize the ship and has been warning nations not to accept it.

The ship had put its destination as Turkey, but later removed it. It’s still in the Mediterranean Sea heading east.
