Throughout the evening, Russian missile and drone strikes have led to blackouts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were wounded while local people in eastern neighborhoods were experienced blackouts and dealt with interruptions to drinking water, as stated by municipal leaders.
Meanwhile, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia area in the southern area, according to local officials.
Moscow has escalated strikes on power infrastructure over recent weeks, while Ukrainian leadership has requested "substantial measures" from allies to exert influence on Moscow.
"What's needed is not window dressing but decisive action - from the US, the EU and the Group of Seven - in providing protection systems and implementing sanctions," mentioned in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 missiles targeted energy facilities, describing such assaults as "premeditated" and against "critical infrastructure" as temperatures become colder.
Government representatives said Moscow was "conducting extensive attacks" and technical staff were working to repair systems.
A series of attacks struck energy infrastructure and apartment buildings in the capital.
Several of the people wounded in the attacks on the capital have been transported for medical care, per statements from city authorities.
Regional authorities said the city came under heavy assaults during nighttime hours. A seven-year-old child was killed and multiple civilians were injured.
The strikes follow evenings of air raids in the territory, sections of which are currently controlled by Moscow's military.
All of Ukraine is in a state of readiness for hypersonic Kinzhal missile strikes, which are harder to spot.
Government officials told the media that Moscow was intentionally trying to demolish the national power system, with attacks already impacting gas facilities.
Authorities confirmed energy workers and government agencies were preparing for further attacks.
