A large-scale Ukrainian drone attack has knocked out all electricity in Kerch, Crimea, forcing the city to rely on backup power while authorities struggle to restore service; the strike has also left nine districts of Crimea without adequate water supply. Russian air defense claims to have intercepted 93 drones across multiple regions including Belgorod, Bryansk, Kursk, Rostov, Moscow, Krasnodar, and the Azov and Black Seas.
