Overnight, Moscow's aerial assaults have led to blackouts in extensive areas of the capital city, Kyiv.
Several individuals were wounded while inhabitants in eastern districts were plunged into darkness and encountered problems to drinking water, as stated by local authorities.
Simultaneously, a seven-year-old child was fatally injured in a different assault in the Zaporizhzhia region in the southern area, as reported by area administrators.
Moscow has escalated assaults on power infrastructure over the past few days, while the country's government has called for "concrete actions" from international partners to apply pressure on Moscow.
"What's needed is not superficial actions but firm measures - from the US, Europe and the major economies - in providing protection systems and applying sanctions," he wrote in a online statement.
He said that hundreds of unmanned aircraft and several dozen projectiles targeted the country's power systems, labeling such strikes as "cynical and calculated" and against "critical infrastructure" as the weather cools.
Government representatives said Moscow was "conducting extensive attacks" and maintenance teams were laboring to fix the damage.
A wave of strikes hit energy infrastructure and apartment buildings in the capital.
Five out of the nine people wounded in the attacks on the city have been transported for medical care, according to local officials.
Regional authorities said the city came under intense attacks overnight. A seven-year-old child was killed and three other people were hurt.
The assaults follow periods of bombing campaigns in the region, parts of which remain under the control of invading troops.
The whole nation is under warning for advanced weapon attacks, which are tougher to detect.
National leaders told the media that Moscow was deliberately attempting to demolish the country's energy grid, with strikes already affecting energy systems.
Officials stated utility staff and government agencies were bracing for additional strikes.
