Overnight, Moscow's missile and drone strikes have resulted in power cuts in multiple districts of the capital city, Kyiv.
Several individuals were injured while local people in eastern districts were plunged into darkness and encountered problems to water systems, as stated by local authorities.
Meanwhile, a young boy was killed in a different assault in the Zaporizhzhia area in the southeastern part, as reported by regional authorities.
Moscow has escalated attacks on power infrastructure over the last fortnight, while the country's government has demanded "concrete actions" from allies to apply pressure on Russia.
"What is required is not symbolic gestures but strong steps - from the United States, the EU and the G7 - in supplying air defence systems and enforcing restrictions," was stated in a social media post.
Authorities reported that numerous aerial vehicles and more than 30 rockets attacked the country's power systems, labeling such attacks as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Moscow was "launching a major assault" and maintenance teams were working to repair systems.
A wave of strikes struck power facilities and apartment buildings in Kyiv.
Multiple people injured in the assaults on the city have been transported for medical care, per statements from city authorities.
Area administrators said the metropolitan region came under heavy assaults overnight. A minor died and multiple civilians were wounded.
The assaults follow nights of bombing campaigns in the area, portions of which are currently controlled by Russian forces.
The entire country is in a state of readiness for sophisticated projectile assaults, which are tougher to identify.
National leaders told the media that Moscow was deliberately attempting to destroy the electrical infrastructure, with attacks already impacting fuel infrastructure.
Authorities confirmed utility staff and authorities were preparing for additional strikes.
