Russian forces have repeatedly used drones to attack civilians and civilian objects in Kherson city in southern Ukraine, serious violations of the laws of war, Human Rights Watch said in a report released today.

A covert Ukrainian operation using FPV drones launched from inside Russia hit targets at at least four Russian air bases, destroying bombers and other aircraft of the country's strategic military aviation.

Video footage shows quadcopter drones striking multiple Tupolev Tu-95 bombers parked in the open, the result of what Ukraine is describing as a clandestine operation that smuggled over a hundred of the weapons deep into Russia.
