Ukrainian naval drones successfully attacked two Russian oil tankers, the Kairos and Virat, in the Black Sea, as confirmed by Ukrainian officials and verified footage. These strikes are part of Ukraine's broader strategy to target Russia's oil revenues, which are crucial for funding its military operations. The attacks occurred off the Turkish coast, with the Kairos hit in the southwest and the Virat struck again the following day. Both vessels are part of Russia's 'shadow fleet,' which consists of tankers used to circumvent Western sanctions imposed after Russia's invasion of Ukraine. The Ukrainian security services reportedly deployed Sea Baby drones for the operation. Turkish authorities responded by attempting to extinguish the fires on the tankers. This escalation serves as a warning to other vessels carrying Russian oil, indicating they may face direct attacks in addition to sanctions. Concurrently, Ukraine is pursuing diplomatic efforts to negotiate an end to the conflict.
