During the night, Moscow's missile and drone strikes have resulted in power cuts in extensive areas of Ukraine's capital, Kyiv.
Several individuals were wounded while local people in the city's east were plunged into darkness and encountered problems to water supplies, according to local authorities.
Meanwhile, a minor was killed in a separate Russian drone strike in the Zaporizhzhia region in the southern area, according to area administrators.
Russian forces has increased attacks on electrical systems over the last fortnight, while the country's government has demanded "substantial measures" from partner nations to increase pressure on Moscow.
"What is required is not window dressing but firm measures - from the America, European nations and the major economies - in delivering air defence systems and implementing penalties," he wrote in a public message.
He said that numerous aerial vehicles and several dozen projectiles struck Ukraine's energy infrastructure, labeling such attacks as "premeditated" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and maintenance teams were striving to fix the damage.
A wave of strikes damaged energy infrastructure and civilian homes in Kyiv.
Five out of the nine people hurt in the attacks on the city have been hospitalized, according to local officials.
Local officials said the city came under heavy assaults during nighttime hours. A young boy was killed and multiple civilians were injured.
The attacks follow nights of bombing campaigns in the area, parts of which remain under the control of Russian forces.
The whole nation is under warning for advanced weapon attacks, which are more difficult to spot.
Government officials told reporters that Russia was purposely seeking to destroy the country's energy grid, with strikes already impacting energy systems.
Officials stated utility staff and officials were preparing for further attacks.
