"During the past night, air defense systems on duty destroyed four Ukrainian unmanned aerial vehicles. Three UAVs were shot down over the territory of the Rostov region, one over the territory of the Voronezh region," it said.
Ukraine has been sending drones and missiles into Russia almost daily since it launched its counteroffensive in early June 2023. The United Nations said in August last year, following a botched drone strike on Moscow, that it did not want to see any targeting of civilian infrastructure.
