Overnight, Moscow's missile and drone strikes have led to electricity outages in large parts of Ukraine's capital, Kyiv.
Several individuals were injured while local people in eastern districts were plunged into darkness and encountered interruptions to water supplies, as stated by local authorities.
Meanwhile, a minor was killed in a separate assault in the Zaporizhzhia area in the southeastern part, based on information from local officials.
Moscow has intensified assaults on power infrastructure over recent weeks, while Ukrainian leadership has called for "concrete actions" from allies to apply pressure on Moscow.
"What's needed is not window dressing but firm measures - from the America, European nations and the Group of Seven - in supplying defensive weapons and enforcing sanctions," mentioned in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 rockets attacked Ukraine's energy infrastructure, labeling such strikes as "cynical and calculated" and against "essential services" as winter approaches.
Government representatives said Russia was "launching a major assault" and maintenance teams were working to restore power.
A wave of strikes damaged electrical systems and civilian homes in the capital.
Several of the people wounded in the strikes on the capital have been hospitalized, as confirmed by city authorities.
Local officials said the city experienced intense attacks overnight. A minor lost their life and multiple civilians were wounded.
The attacks succeed evenings of air raids in the area, parts of which are occupied by Russian forces.
All of Ukraine is under warning for hypersonic Kinzhal missile strikes, which are tougher to spot.
Government officials told reporters that Russia was purposely seeking to damage the country's energy grid, with assaults already affecting fuel infrastructure.
Authorities confirmed energy workers and government agencies were bracing for more assaults.
