Overnight, Moscow's aerial assaults have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
Several individuals were injured while local people in eastern districts were plunged into darkness and faced disruption to drinking water, as stated by local authorities.
At the same time, a young boy was lost their life in a separate assault in the Zaporizhzhia region in the country's south-east, according to area administrators.
Moscow has intensified attacks on power infrastructure over recent weeks, while the country's government has demanded "concrete actions" from partner nations to exert influence on Russia.
"What's needed is not superficial actions but strong steps - from the United States, European nations and the major economies - in delivering air defence systems and implementing restrictions," he wrote in a social media post.
He said that numerous aerial vehicles and more than 30 missiles attacked Ukraine's energy infrastructure, describing such strikes as "strategic and deliberate" and against "essential services" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were laboring to repair systems.
A wave of strikes damaged energy infrastructure and residential structures in Kyiv.
Five out of the nine people injured in the attacks on the capital have been transported for medical care, per statements from city authorities.
Area administrators said the urban area came under heavy assaults during nighttime hours. A young boy died and multiple civilians were injured.
The attacks come after periods of aerial attacks in the region, portions of which are occupied by invading troops.
All of Ukraine is on alert for hypersonic Kinzhal missile strikes, which are more difficult to detect.
Authorities told reporters that Russia was purposely seeking to demolish the electrical infrastructure, with attacks already impacting fuel infrastructure.
He said utility staff and government agencies were preparing for additional strikes.
