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.

In the latest drone strikes on Russian critical infrastructure, Ukraine has attacked a manufacturing unit in Cheboksary that makes critical components for Russian missiles and Iranian suicide drones.

A large Russian drone-and-missile attack targeted Ukraine's eastern city of Kharkiv on Saturday, killing at least three people and injuring 21, local Ukrainian officials said. The Russian barrage — the latest in near daily widescale attacks by Moscow — included deadly aerial glide bombs that have become part of fierce Russian attacks in the three-year war.
