Overnight, Russian aerial assaults have caused blackouts in large parts of Ukraine's capital, Kyiv.
A number of civilians were wounded while residents in eastern neighborhoods were left without electricity and encountered disruption to water systems, according to local authorities.
Simultaneously, a seven-year-old child was fatally injured in a separate Russian drone strike in the Zaporizhzhia region in the southeastern part, based on information from local officials.
Russian forces has intensified strikes on energy facilities over recent weeks, while Ukrainian leadership has called for "substantial measures" from allies to apply pressure on Russia.
"What is required is not symbolic gestures but firm measures - from the America, Europe and the major economies - in supplying defensive weapons and applying restrictions," he wrote in a public message.
Officials stated that hundreds of unmanned aircraft and several dozen missiles struck Ukraine's energy infrastructure, describing such strikes as "strategic and deliberate" and against "critical infrastructure" as temperatures become colder.
Energy officials said Moscow was "inflicting a massive strike" and technical staff were striving to restore power.
A barrage of missiles struck power facilities and residential structures in the capital.
Several of the people injured in the strikes on the city have been transported for medical care, according to municipal representatives.
Regional authorities said the urban area endured intense attacks during nighttime hours. A minor died and several individuals were wounded.
The strikes follow periods of bombing campaigns in the territory, portions of which are currently controlled by Moscow's military.
The entire country is on alert for advanced weapon attacks, which are tougher to spot.
Authorities told reporters that Russia was deliberately attempting to demolish the country's energy grid, with attacks already impacting gas facilities.
Authorities confirmed energy workers and authorities were anticipating additional strikes.
