During the night, Russian missile and drone strikes have led to electricity outages in extensive areas of Ukraine's capital, the Ukrainian capital.
A number of civilians were injured while residents in eastern districts were experienced blackouts and faced problems to water supplies, as stated by local authorities.
Simultaneously, a minor was fatally injured in a distinct assault in the southeastern region in the southeastern part, according to regional authorities.
Moscow has increased strikes on power infrastructure over the last fortnight, while the country's government has demanded "substantial measures" from international partners to exert influence on Russia.
"What is required is not superficial actions but firm measures - from the United States, the EU and the Group of Seven - in providing air defence systems and enforcing penalties," he wrote in a public message.
Authorities reported that 450 drones and several dozen missiles targeted Ukraine's energy infrastructure, labeling such assaults as "cynical and calculated" and against "essential services" as temperatures become colder.
Energy officials said Russia was "conducting extensive attacks" and technical staff were striving to repair systems.
A wave of strikes struck power facilities and residential structures in the capital.
Several of the people injured in the assaults on the capital have been taken to hospital, as confirmed by city authorities.
Area administrators said the urban area came under intense attacks overnight. A seven-year-old child lost their life and three other people were hurt.
The attacks follow periods of air raids in the territory, parts of which are occupied by Moscow's military.
The whole nation is on alert for hypersonic Kinzhal missile strikes, which are more difficult to spot.
Authorities told the media that Moscow was deliberately attempting to damage the country's energy grid, with strikes already disrupting energy systems.
He said energy workers and government agencies were anticipating additional strikes.
