During the night, Moscow's missile and drone strikes have led to power cuts in extensive areas of the capital city, Kyiv.
Nine people were wounded while local people in eastern districts were left without electricity and faced disruption to water supplies, per reports from city officials.
Meanwhile, a seven-year-old child was fatally injured in a different Russian drone strike in the Zaporizhzhia region in the country's south-east, based on information from area administrators.
Moscow has intensified assaults on electrical systems over recent weeks, while officials has requested "substantial measures" from allies to exert influence on Moscow.
"What's needed is not symbolic gestures but strong steps - from the America, European nations and the G7 - in providing air defence systems and applying restrictions," he wrote in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 rockets struck energy facilities, labeling such attacks as "premeditated" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "launching a major assault" and technical staff were working to fix the damage.
A barrage of missiles damaged energy infrastructure and apartment buildings in Kyiv.
Five out of the nine people wounded in the assaults on the city have been transported for medical care, according to municipal representatives.
Regional authorities said the metropolitan region came under intense attacks overnight. A seven-year-old child lost their life and several individuals were injured.
The assaults come after evenings of aerial attacks in the area, sections of which are occupied by Russian forces.
The entire country is on alert for advanced weapon attacks, which are more difficult to identify.
Government officials told the media that Russia was intentionally trying to damage the country's energy grid, with attacks already impacting fuel infrastructure.
He said technical personnel and authorities were preparing for further attacks.
