During the night, Moscow's aerial assaults have caused electricity outages in extensive areas of the capital city, Kyiv.
A number of civilians were wounded while inhabitants in the city's east were left without electricity and faced disruption to drinking water, according to municipal leaders.
Meanwhile, a young boy was killed in a distinct aerial attack in the Zaporizhzhia region in the southeastern part, based on information from regional authorities.
Russian forces has increased assaults on energy facilities over recent weeks, while Ukrainian leadership has called for "real steps" from allies to apply pressure on Moscow.
"What is required is not superficial actions but decisive action - from the America, Europe and the G7 - in supplying air defence systems and applying sanctions," he wrote in a public message.
He said that numerous aerial vehicles and more than 30 missiles targeted the country's power systems, characterizing such strikes as "strategic and deliberate" and against "essential services" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and repair crews were striving to restore power.
A wave of strikes hit energy infrastructure and apartment buildings in Kyiv.
Five out of the nine people wounded in the strikes on the city have been transported for medical care, according to city authorities.
Area administrators said the city experienced intense attacks throughout the evening. A young boy was killed and multiple civilians were hurt.
The attacks come after evenings of bombing campaigns in the region, parts of which remain under the control of invading troops.

Government officials told the media that Russia was deliberately attempting to destroy the electrical infrastructure, with attacks already impacting energy systems.
Officials stated energy workers and authorities were bracing for further attacks.
