During the night, Moscow's missile and drone strikes have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
Several individuals were hurt while residents in eastern districts were plunged into darkness and encountered disruption to water supplies, according to city officials.
At the same time, a young boy was fatally injured in a distinct Russian drone strike in the southeastern region in the country's south-east, according to regional authorities.
Moscow has escalated assaults on electrical systems over recent weeks, while the country's government has requested "substantial measures" from international partners to apply pressure on Russia.
"What is required is not window dressing but decisive action - from the America, European nations and the Group of Seven - in providing protection systems and applying restrictions," was stated in a public message.
Authorities reported that numerous aerial vehicles and several dozen projectiles attacked the country's power systems, labeling such strikes as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were striving to fix the damage.
A wave of strikes damaged energy infrastructure and civilian homes in the capital.
Multiple people hurt in the attacks on the city have been taken to hospital, according to local officials.
Area administrators said the urban area endured significant strikes throughout the evening. A seven-year-old child lost their life and three other people were hurt.
The attacks succeed evenings of bombing campaigns in the region, portions of which are occupied by Russian forces.
The whole nation is in a state of readiness for hypersonic Kinzhal missile strikes, which are harder to spot.
Government officials told reporters that Moscow was deliberately attempting to damage the national power system, with attacks already affecting energy systems.
Officials stated technical personnel and government agencies were anticipating additional strikes.
