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 hurt while inhabitants in the city's east were experienced blackouts and encountered disruption to water supplies, per reports from city officials.
At the same time, a seven-year-old child was killed in a different aerial attack in the southeastern region in the southern area, based on information from local officials.
Moscow has escalated attacks on energy facilities over the last fortnight, while Ukrainian leadership has called for "real steps" from partner nations to apply pressure on Moscow.
"The necessity is not superficial actions but decisive action - from the America, the EU and the Group of Seven - in delivering protection systems and implementing restrictions," was stated in a online statement.
Authorities reported that 450 drones and several dozen rockets targeted energy facilities, characterizing such assaults as "premeditated" and against "essential services" as the weather cools.
The energy minister said Russia was "launching a major assault" and repair crews were laboring to repair systems.
A wave of strikes hit power facilities and civilian homes in the capital.
Five out of the nine people wounded in the assaults on the city have been taken to hospital, per statements from city authorities.
Regional authorities said the city endured significant strikes overnight. A young boy was killed and three other people were injured.
The assaults follow evenings of bombing campaigns in the area, parts of which remain under the control of invading troops.
All of Ukraine is in a state of readiness for hypersonic Kinzhal missile strikes, which are more difficult to spot.
Government officials told journalists that Russia was intentionally trying to destroy the country's energy grid, with attacks already disrupting fuel infrastructure.
He said technical personnel and authorities were bracing for further attacks.
