Officials stated that 450 drones and over thirty rockets attacked energy facilities, characterizing such assaults as "strategic and deliberate" and against "critical infrastructure" as temperatures become colder.

A barrage of missiles damaged power facilities and apartment buildings in Kyiv.
Five out of the nine people hurt in the strikes on the city have been taken to hospital, according to municipal representatives.
