Overnight, Moscow's missile and drone strikes have caused power cuts in extensive areas of Ukraine's capital, Kyiv.
Several individuals were hurt while residents in eastern districts were plunged into darkness and faced disruption to drinking water, according to municipal leaders.
Meanwhile, a minor was lost their life in a different Russian drone strike in the southeastern region in the southern area, according to area administrators.
Moscow has increased assaults on energy facilities over the last fortnight, while Ukrainian leadership has called for "concrete actions" from international partners to apply pressure on Moscow.
"What is required is not symbolic gestures but strong steps - from the US, the EU and the G7 - in delivering protection systems and implementing restrictions," he wrote in a online statement.
Authorities reported that 450 drones and several dozen projectiles attacked the country's power systems, labeling such assaults as "premeditated" and against "essential services" as the weather cools.
Government representatives said Moscow was "launching a major assault" and repair crews were laboring to repair systems.
A barrage of missiles damaged energy infrastructure and apartment buildings in the capital.
Five out of the nine people injured in the strikes on the capital have been hospitalized, as confirmed by local officials.
Regional authorities said the city experienced heavy assaults during nighttime hours. A seven-year-old child died and multiple civilians were injured.
The assaults come after nights of aerial attacks in the territory, parts of which are occupied by invading troops.
All of Ukraine is on alert for hypersonic Kinzhal missile strikes, which are harder to detect.
National leaders told the media that Russia was deliberately attempting to damage the country's energy grid, with strikes already affecting fuel infrastructure.
Authorities confirmed technical personnel and authorities were preparing for further attacks.
