During the night, Russian aerial assaults have caused power cuts in extensive areas of the capital city, Kyiv.
A number of civilians were wounded while residents in eastern districts were left without electricity and encountered interruptions to drinking water, according to municipal leaders.
Meanwhile, a young boy was fatally injured in a distinct Russian drone strike in the southeastern region in the country's south-east, as reported by area administrators.
Moscow has escalated attacks on power infrastructure over recent weeks, while the country's government has demanded "substantial measures" from international partners to increase pressure on Moscow.
"The necessity is not window dressing but decisive action - from the United States, the EU and the G7 - in supplying defensive weapons and implementing restrictions," he wrote in a public message.
Authorities reported that hundreds of unmanned aircraft and over thirty rockets struck energy facilities, characterizing such attacks as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "inflicting a massive strike" and maintenance teams were working to repair systems.
A barrage of missiles hit power facilities and apartment buildings in the capital.
Five out of the nine people hurt in the strikes on the city have been transported for medical care, according to municipal representatives.
Regional authorities said the urban area experienced intense attacks during nighttime hours. A seven-year-old child died and multiple civilians were wounded.
The strikes succeed periods of aerial attacks in the region, parts of which are occupied by invading troops.
The whole nation is in a state of readiness for advanced weapon attacks, which are tougher to spot.
Authorities told the media that Moscow was deliberately attempting to destroy the country's energy grid, with strikes already disrupting energy systems.
He said technical personnel and authorities were bracing for additional strikes.
