During the night, Moscow's aerial assaults have led to blackouts in multiple districts of Ukraine's capital, the Ukrainian capital.
A number of civilians were hurt while local people in eastern neighborhoods were experienced blackouts and faced disruption to drinking water, according to city officials.
Simultaneously, a seven-year-old child was fatally injured in a different Russian drone strike in the southeastern region in the country's south-east, according to regional authorities.
Russian forces has intensified attacks on energy facilities over recent weeks, while Ukrainian leadership has requested "real steps" from partner nations to apply pressure on Moscow.
"What is required is not window dressing but firm measures - from the US, the EU and the major economies - in delivering protection systems and enforcing penalties," he wrote in a online statement.
Authorities reported that 450 drones and several dozen missiles struck energy facilities, describing such assaults as "cynical and calculated" and against "essential services" as temperatures become colder.
The energy minister said Moscow was "inflicting a massive strike" and repair crews were laboring to fix the damage.
A barrage of missiles hit energy infrastructure and apartment buildings in the capital.
Five out of the nine people injured in the assaults on the city have been transported for medical care, as confirmed by municipal representatives.
Local officials said the metropolitan region experienced intense attacks overnight. A minor lost their life and three other people were wounded.
The assaults come after periods of air raids in the region, parts of which remain under the control of invading troops.
The entire country is in a state of readiness for advanced weapon attacks, which are tougher to spot.
National leaders told the media that Moscow was intentionally trying to demolish the electrical infrastructure, with attacks already affecting fuel infrastructure.
Authorities confirmed energy workers and officials were preparing for additional strikes.
