During the night, Moscow's missile and drone strikes have led to power cuts in extensive areas of the capital city, Kyiv.
Several individuals were hurt while residents in eastern neighborhoods were left without electricity and faced disruption to water systems, according to city officials.
Meanwhile, a seven-year-old child was fatally injured in a distinct Russian drone strike in the southeastern region in the country's south-east, according to local officials.
Russian forces has escalated assaults on energy facilities over recent weeks, while officials has demanded "substantial measures" from allies to exert influence on Moscow.
"The necessity is not superficial actions but decisive action - from the United States, the EU and the major economies - in supplying air defence systems and implementing penalties," mentioned in a social media post.
Authorities reported that 450 drones and more than 30 rockets targeted Ukraine's energy infrastructure, characterizing such strikes as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
The energy minister said Moscow was "inflicting a massive strike" and repair crews were laboring to restore power.
A wave of strikes damaged energy infrastructure and civilian homes in the capital.
Five out of the nine people injured in the attacks on the city have been taken to hospital, per statements from city authorities.
Area administrators said the city experienced intense attacks throughout the evening. A minor lost their life and three other people were injured.
The strikes follow evenings of bombing campaigns in the territory, sections of which are occupied by Moscow's military.
The entire country is under warning for advanced weapon attacks, which are more difficult to spot.
Authorities told reporters that Russia was deliberately attempting to demolish the national power system, with attacks already affecting fuel infrastructure.
Authorities confirmed utility staff and government agencies were anticipating more assaults.
