Overnight, Moscow's missile and drone strikes have caused blackouts in multiple districts of Ukraine's capital, Kyiv.
Several individuals were wounded while residents in eastern districts were left without electricity and dealt with interruptions to water supplies, according to city officials.
Simultaneously, a seven-year-old child was fatally injured in a different assault in the Zaporizhzhia region in the southern area, according to regional authorities.
Moscow has intensified strikes on electrical systems over the past few days, while officials has called for "real steps" from allies to exert influence on Russia.
"What is required is not window dressing but firm measures - from the America, the EU and the Group of Seven - in providing protection systems and implementing restrictions," mentioned in a social media post.
Officials stated that 450 drones and several dozen rockets struck energy facilities, characterizing such attacks as "strategic and deliberate" and against "essential services" as temperatures become colder.
The energy minister said Moscow was "conducting extensive attacks" and technical staff were laboring to fix the damage.
A series of attacks damaged electrical systems and residential structures in Kyiv.
Several of the people wounded in the attacks on the city have been hospitalized, according to city authorities.
Area administrators said the metropolitan region experienced intense attacks during nighttime hours. A seven-year-old child was killed and three other people were wounded.
The attacks come after evenings of aerial attacks in the territory, parts of which are occupied by Russian forces.
The entire country is on alert for sophisticated projectile assaults, which are more difficult to spot.
National leaders told journalists that Moscow was purposely seeking to demolish the electrical infrastructure, with strikes already disrupting gas facilities.
Officials stated technical personnel and government agencies were preparing for additional strikes.
