Authorities reported that hundreds of unmanned aircraft and more than 30 missiles attacked Ukraine's energy infrastructure, describing such assaults as "strategic and deliberate" and against "everything that sustains normal life" as the weather cools.
The energy minister said Moscow was "inflicting a massive strike" and repair crews were striving to repair systems.
A barrage of missiles struck power facilities and apartment buildings in Kyiv.
Several of the people wounded in the assaults on the capital have been transported for medical care, as confirmed by city authorities.
Area administrators said the city came under intense attacks during nighttime hours. A young boy was killed and several individuals were wounded.
The strikes come after evenings of air raids in the territory, portions of which are currently controlled by Moscow's military.
