Ukraine said its drones hit a Russian research and production facility that supplies components for missiles, as Russia unleashed a fresh barrage of air attacks overnight.

Ukraine attacks an electronics plant in Chuvashia, 1,300 km from the border. The Ukrainian Air Force has reported that Russia has launched 479 explosive drones over its territory during the night and 20 missiles in the most extensive attack since the beginning of the war.

Ukraine says that a large Russian drone-and-missile attack has targeted the city of Kharkiv, killing at least three people and injuring 21.
