Melnichenko confirmed the attack and a fire at "one of the industrial facilities".

Quote from Melnichenko : "Enemy drones attacked one of our industrial facilities once again. No casualties or destruction have been recorded. A fire has broken out on the premises, which is now being extinguished. I am at the scene, where emergency services are working."

Details : Melnichenko added that temporary mobile internet restrictions have been introduced in the oblast supposedly "due to safety reasons".

He claimed this "helps servicemen suppress drones".
