Authorities reported that 450 drones and several dozen rockets targeted Ukraine's energy infrastructure, labeling such attacks as "strategic and deliberate" and against "essential services" as the weather cools.

A series of attacks damaged electrical systems and civilian homes in Kyiv.
Multiple people hurt in the attacks on the city have been taken to hospital, as confirmed by local officials.

The strikes come after evenings of aerial attacks in the area, portions of which are occupied by invading troops.
