Overnight, Moscow's aerial assaults have led to power cuts in large parts of Ukraine's capital, Kyiv.
Nine people were wounded while local people in eastern districts were left without electricity and encountered disruption to drinking water, as stated by local authorities.
At the same time, a minor was killed in a distinct assault in the Zaporizhzhia area in the country's south-east, based on information from regional authorities.
Russian forces has escalated attacks on power infrastructure over the last fortnight, while the country's government has demanded "concrete actions" from partner nations to apply pressure on Moscow.
"The necessity is not superficial actions but firm measures - from the United States, European nations and the major economies - in supplying defensive weapons and applying penalties," he wrote in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 projectiles struck Ukraine's energy infrastructure, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as winter approaches.
Energy officials said Moscow was "conducting extensive attacks" and repair crews were working to restore power.
A series of attacks struck electrical systems and civilian homes in Kyiv.
Five out of the nine people wounded in the strikes on the city have been transported for medical care, as confirmed by local officials.
Local officials said the urban area experienced intense attacks overnight. A seven-year-old child was killed and three other people were wounded.
The strikes follow nights of bombing campaigns in the region, parts of which are occupied by Moscow's military.
The entire country is on alert for sophisticated projectile assaults, which are harder to identify.
Government officials told journalists that Moscow was intentionally trying to demolish the national power system, with assaults already affecting energy systems.
Authorities confirmed utility staff and government agencies were preparing for more assaults.
