Russia said its forces had downed 75 Ukrainian drones overnight, with nearly 50 destroyed over the southern Rostov region.
Air defence systems intercepted 47 drones over Rostov, 17 over the Black and Azov seas and 11 in other areas including one over the frontier region of Belgorod.
There were no casualties, according to preliminary information.
Russia almost daily announces the interception of Ukrainian drones which Kyiv says are a response to Russian attacks aimed at military and civilian targets since Moscow launched its special military operation in February 2022.
