Throughout the evening, Russian missile and drone strikes have resulted in power cuts in large parts of Ukraine's capital, Kyiv.
A number of civilians were wounded while inhabitants in eastern neighborhoods were experienced blackouts and encountered interruptions to water supplies, according to municipal leaders.
Meanwhile, a minor was fatally injured in a different assault in the Zaporizhzhia region in the southeastern part, based on information from local officials.
Russian forces has intensified attacks on energy facilities over the past few days, while the country's government has demanded "concrete actions" from international partners to increase pressure on Moscow.
"What is required is not symbolic gestures but decisive action - from the United States, European nations and the major economies - in providing air defence systems and enforcing restrictions," he wrote in a online statement.
Authorities reported that 450 drones and several dozen projectiles targeted energy facilities, labeling such strikes as "cynical and calculated" and against "essential services" as temperatures become colder.
Government representatives said Russia was "inflicting a massive strike" and maintenance teams were working to repair systems.
A wave of strikes damaged electrical systems and residential structures in the capital.
Five out of the nine people injured in the strikes on the capital have been transported for medical care, as confirmed by city authorities.
Local officials said the metropolitan region experienced heavy assaults during nighttime hours. A young boy was killed and several individuals were wounded.
The strikes follow evenings of air raids in the territory, sections of which remain under the control of Moscow's military.
The entire country is in a state of readiness for advanced weapon attacks, which are more difficult to identify.
Authorities told the media that Russia was purposely seeking to demolish the national power system, with assaults already affecting gas facilities.
Authorities confirmed utility staff and government agencies were preparing for more assaults.
