Overnight, Moscow's missile and drone strikes have caused electricity outages in multiple districts of the capital city, Kyiv.
Several individuals were hurt while local people in eastern districts were plunged into darkness and faced disruption to drinking water, per reports from city officials.
Meanwhile, a young boy was lost their life in a separate assault in the southeastern region in the country's south-east, based on information from local officials.
Moscow has intensified attacks on power infrastructure over recent weeks, while officials has called for "concrete actions" from international partners to exert influence on Russia.
"What is required is not superficial actions but decisive action - from the US, the EU and the Group of Seven - in delivering air defence systems and enforcing restrictions," he wrote in a social media post.
Authorities reported that hundreds of unmanned aircraft and several dozen projectiles struck energy facilities, labeling such assaults as "cynical and calculated" and against "critical infrastructure" as the weather cools.
Energy officials said Russia was "launching a major assault" and maintenance teams were striving to restore power.
A barrage of missiles damaged energy infrastructure and apartment buildings in Kyiv.
Five out of the nine people hurt in the strikes on the capital have been hospitalized, as confirmed by municipal representatives.
Area administrators said the metropolitan region endured heavy assaults overnight. A minor was killed and multiple civilians were hurt.
The assaults succeed nights of bombing campaigns in the territory, parts of which remain under the control of invading troops.
