KYIV, Dec 15 (Reuters) - Ukraine said on Monday it hit and disabled a Russian missile-carrying submarine docked at a Black Sea naval base using underwater sea drones for the first time, but Moscow denied the strike caused any damage.

The attack with Ukrainian-made "Sub Sea Baby" drones hit the submarine in the port of Novorossiysk where Russia has rebased many of its Black Sea naval vessels to put them out of reach of Ukrainian strikes, the Security Service of Ukraine (SBU) said.
