Overnight, Moscow's missile and drone strikes have caused blackouts in extensive areas of Ukraine's capital, Kyiv.
Nine people were wounded while inhabitants in eastern neighborhoods were experienced blackouts and dealt with interruptions to water systems, as stated by city officials.
Meanwhile, a seven-year-old child was fatally injured in a separate Russian drone strike in the Zaporizhzhia region in the country's south-east, according to regional authorities.
Moscow has increased attacks on electrical systems over recent weeks, while Ukrainian leadership has called for "concrete actions" from allies to increase pressure on Moscow.
"What is required is not symbolic gestures but decisive action - from the America, the EU and the G7 - in providing air defence systems and enforcing penalties," mentioned in a online statement.
Authorities reported that hundreds of unmanned aircraft and over thirty missiles struck energy facilities, describing such attacks as "premeditated" and against "essential services" as the weather cools.
Government representatives said Russia was "inflicting a massive strike" and maintenance teams were working to fix the damage.
A series of attacks damaged energy infrastructure and apartment buildings in the capital.
Multiple people hurt in the strikes on the city have been transported for medical care, per statements from local officials.
Area administrators said the metropolitan region came under significant strikes throughout the evening. A minor died and three other people were wounded.
The assaults come after nights of bombing campaigns in the region, sections of which are currently controlled by Russian forces.
The whole nation is on alert for sophisticated projectile assaults, which are tougher to identify.
Authorities told journalists that Moscow was purposely seeking to demolish the country's energy grid, with strikes already impacting gas facilities.
Authorities confirmed technical personnel and government agencies were bracing for further attacks.
