Russia dispatched a destroyer-class warship to Syria on Tuesday from its Black Sea fleet, a source in the Russian Navy told Reuters.

Destroyer Smetlivy, which patrolled waters off the coast of Syria in April and May, was seen leaving the Black Sea port of Sevastopol on Tuesday morning.

"The vessel is expected to reach the Turkish straits tomorrow morning," the source said, speaking on condition of anonymity, adding that the ship was heading to Syria.

The navy declined to confirm its destination.

"The vessel has gone to sea, I cannot tell you anything else," Vyacheslav Trukhachyov, a spokesman for Russia's Black Sea Fleet, said. – Reuters
