“A UAV (unmanned aerial vehicle) crashed in an industrial zone. One person was injured and is receiving all necessary medical assistance,” Artamonov said on the Telegram messaging app.

The Russian defence ministry said on Telegram that its units destroyed 55 Ukrainian drones overnight over five Russian regions and the Black Sea, including three over the Lipetsk region.

The full damage of the attack on Russia was not immediately known. There was no immediate comment from Ukraine about the attack.

Both sides deny targeting civilians in their strikes during the war that Russia launched against Ukraine more than three years ago. But thousands of civilians have died in the conflict, the vast majority of them Ukrainian.

Ukraine has launched multiple air strikes on Lipetsk, a strategically important region with an air base that is the chief training centre for the Russian Aerospace Forces.
