The Russian Defence Ministry said on Friday that 33 Ukrainian drones had been intercepted and destroyed over five Russian regions, Crimea and the Black sea overnight.
At least eight Russian airports had been forced to suspend operations during the night, according to Russia's aviation watchdog.
Two people had been injured in the city of Slavyansk-on-Kuban in the Krasnodar region in southern Russia and classes at schools and kindergartens had been suspended due to a drone attack, the local emergencies centre said.
In the Rostov region, where seven drones had been downed, an electricity pylon was damaged, leaving over 200 houses without power, Yuri Slyusar, the local governor, wrote on the Telegram messaging app.
