Throughout the evening, Russian missile and drone strikes have led to electricity outages in large parts of Ukraine's capital, Kyiv.
A number of civilians were wounded while inhabitants in eastern districts were plunged into darkness and encountered interruptions to drinking water, according to city officials.
Meanwhile, a minor was lost their life in a different Russian drone strike in the Zaporizhzhia area in the southeastern part, based on information from area administrators.
Moscow has intensified assaults on electrical systems over recent weeks, while officials has demanded "concrete actions" from partner nations to exert influence on Russia.
"The necessity is not superficial actions but strong steps - from the United States, the EU and the Group of Seven - in supplying air defence systems and enforcing restrictions," he wrote in a public message.
Authorities reported that 450 drones and more than 30 projectiles struck Ukraine's energy infrastructure, characterizing such assaults as "premeditated" and against "essential services" as temperatures become colder.
The energy minister said Russia was "conducting extensive attacks" and technical staff were striving to repair systems.
A wave of strikes hit energy infrastructure and residential structures in the capital.
Five out of the nine people injured in the strikes on the capital have been transported for medical care, per statements from city authorities.
Area administrators said the urban area experienced intense attacks overnight. A young boy died and multiple civilians were wounded.
The assaults come after nights of air raids in the region, portions of which are currently controlled by Russian forces.
All of Ukraine is on alert for sophisticated projectile assaults, which are harder to spot.
Government officials told journalists that Moscow was intentionally trying to damage the country's energy grid, with strikes already impacting energy systems.
Officials stated energy workers and government agencies were anticipating more assaults.
