Throughout the evening, Moscow's missile and drone strikes have caused power cuts in multiple districts of Ukraine's capital, the Ukrainian capital.
A number of civilians were injured while inhabitants in the city's east were plunged into darkness and faced interruptions to water supplies, per reports from municipal leaders.
Meanwhile, a seven-year-old child was fatally injured in a distinct aerial attack in the southeastern region in the country's south-east, as reported by area administrators.
Moscow has escalated assaults on energy facilities over recent weeks, while the country's government has called for "real steps" from allies to exert influence on Russia.
"What is required is not window dressing but decisive action - from the US, European nations and the G7 - in providing protection systems and implementing restrictions," he wrote in a online statement.
Officials stated that 450 drones and over thirty rockets targeted Ukraine's energy infrastructure, describing such assaults as "cynical and calculated" and against "critical infrastructure" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and maintenance teams were working to repair systems.
A series of attacks struck power facilities and civilian homes in the capital.
Several of the people wounded in the assaults on the city have been transported for medical care, as confirmed by municipal representatives.
Regional authorities said the metropolitan region experienced heavy assaults overnight. A minor lost their life and several individuals were injured.
The assaults follow evenings of bombing campaigns in the area, portions of which are occupied by Moscow's military.
All of Ukraine is on alert for advanced weapon attacks, which are tougher to detect.
Authorities told reporters that Russia was intentionally trying to destroy the national power system, with attacks already impacting fuel infrastructure.
Authorities confirmed technical personnel and government agencies were preparing for more assaults.
