KYIV, Nov 29 (Reuters) - Ukrainian naval drones hit two sanctioned tankers in the Black Sea as they headed to a Russian port to load up with oil destined for foreign markets, an official said on Saturday, as Kyiv tries to pile pressure on Russia's vast oil industry.
The two oil tankers, identified as the Kairos and Virat, were empty and sailing to Novorossiysk, a major Russian Black Sea oil terminal, the official at the Security Service of Ukraine told Reuters.
