The drone raids marked Kyiv's attempt to strike back during Moscow's offensive in northeastern Ukraine, which has added to the pressure on outnumbered and outgunned Ukrainian forces who are waiting for delayed deliveries of crucial weapons and ammunition from Western partners.
The Russian Defense Ministry said air defenses downed 51 Ukrainian drones over Crimea, another 44 over the Krasnodar region and six over the Belgorod region. It said Russian warplanes and patrol boats also destroyed six sea drones in the Black Sea.
Mikhail Razvozhayev, the governor of Sevastopol, which is the main base of Russia's Black Sea Fleet, said the drone attack damaged the city's power plant. He said it could take a day to restore energy supplies and announced schools in the city would be closed temporarily.
