(Reuters) -Overnight missile and bomb strikes by Russia on the Ukrainian city of Kharkiv left three people dead and 22 hurt, while a Ukrainian drone attack in the Moscow region wounded two people, officials from both countries said separately on Saturday.

The drones are typically attached to RPG-7 shaped charges or fragmentation grenades, capable of inflicting serious damage to armored vehicles, aircraft, and infrastructure.
