During the night, Russian missile and drone strikes have resulted in power cuts in extensive areas of the capital city, Kyiv.
A number of civilians were injured while inhabitants in the city's east were left without electricity and dealt with interruptions to water supplies, as stated by local authorities.
At the same time, a young boy was lost their life in a separate Russian drone strike in the Zaporizhzhia area in the country's south-east, based on information from local officials.
Moscow has intensified attacks on energy facilities over the past few days, while officials has requested "substantial measures" from international partners to apply pressure on Russia.
"What is required is not superficial actions but firm measures - from the US, Europe and the Group of Seven - in supplying protection systems and applying restrictions," he wrote in a social media post.
Authorities reported that hundreds of unmanned aircraft and over thirty projectiles targeted energy facilities, describing such assaults as "strategic and deliberate" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Russia was "launching a major assault" and maintenance teams were striving to restore power.
A barrage of missiles damaged energy infrastructure and residential structures in Kyiv.
Five out of the nine people wounded in the attacks on the city have been hospitalized, per statements from local officials.
Area administrators said the urban area came under significant strikes during nighttime hours. A minor lost their life and three other people were injured.
The assaults come after periods of aerial attacks in the region, portions of which are occupied by Russian forces.
The entire country is under warning for sophisticated projectile assaults, which are harder to spot.
National leaders told the media that Moscow was deliberately attempting to damage the electrical infrastructure, with strikes already impacting energy systems.
Authorities confirmed technical personnel and government agencies were preparing for further attacks.
