Watch I Video shows Russian warship being towed after sea drone attack by Ukraine

The news agency Reuters reported citing two sources familiar with the matter that a Russian warship was seriously damaged in an overnight Ukrainian naval drone attack.

The video has been shared by a source at Ukraine's security service. In the video, a drone can be seen moving across the Black Sea and approaching the Russian vessel.

The Ukrainian intelligence sources have told various news outlets that the Olenegorsky Gornyak, which is a "landing ship" was hit. The vessel was reportedly designed to carry equipment and personnel for beach landings.

The source also said that there was a crew of around 100 Russian servicemen on the vessel when it was attacked by a sea drone carrying 450kgof TNT. Authorities have not provided any information about damage or casualties.

But according to a source with knowledge of the port's operations, a large Russian naval vessel had to be towed ashore because it could not move under its own power after being damaged.

Earlier in a statement, Russia's Defence Ministry said that the Ukrainian attack by two sea drones had been repelled in the waters outside the base. The ministry had also claimed that the drones had been destroyed.

The Caspian Pipeline Consortium, which operates an oil terminal there, said that Novorossiysk is the civilian port, which handles two per cent of the world's oil supply and also exports grain.

It said that all ship movement was temporarily halted, but normal operations were resumed later.
