A Russian Navy ship is seen listing heavily and being towed near a Black Sea naval base in videos circulating on social media Friday after the Russian Defense Ministry claimed it had foiled a Ukrainian sea drone attack.

The videos appear to identify the vessel being towed as the Russian landing ship Olenegorsky Gornyak. Several Russian bloggers also identified the vessel as the Olenegorsky Gornyak.

CNN has been provided with video that shows an unmanned sea drone approaching a ship that appears to match the identity of the Russian naval vessel seen listing in the port of Novorossiysk.

The 36-second video, shot from the sea drone itself, shows it approaching a ship at night. The video ends just as the drone reaches the ship.

CNN is unable to conclusively verify the ship's identity.

 In a statement earlier Friday, the Russian Defense Ministry said two uncrewed boats targeted the Novorossiysk naval base in Krasnodar province, but the attack was repelled by Russian ships.

The ministry also said it downed 10 Ukrainian drones over Crimea, the peninsula illegally annexed by Russia from Ukraine in 2014.
