The drone attack on Monday night was a special operation aimed at an aircraft depot at the Saky airbase on the annexed peninsula, according to SBU.
A Su-30 model aircraft was completely destroyed and another was damaged. Three more aircraft, of the Su-24 model, and an ammunition depot were hit in the attack.
The Saky airbase plays a central role in the Black Sea area and the damage after the Ukrainian attack is considered by SBU as "significant".
The information has not been confirmed by independent sources. The Russian Ministry of Defense claims that 61 Ukrainian drones were shot down on Monday night, of which 18 flew over the Black Sea, reports the Spanish news agency EFE.
