Overnight, Russian missile and drone strikes have caused blackouts in multiple districts of Ukraine's capital, Kyiv.
Nine people were hurt while residents in the city's east were experienced blackouts and faced problems to water systems, according to city officials.
Meanwhile, a minor was killed in a distinct assault in the Zaporizhzhia area in the southern area, based on information from local officials.
Moscow has increased assaults on power infrastructure over the last fortnight, while the country's government has called for "concrete actions" from partner nations to apply pressure on Moscow.
"What's needed is not symbolic gestures but firm measures - from the America, European nations and the Group of Seven - in providing air defence systems and enforcing restrictions," mentioned in a online statement.
He said that numerous aerial vehicles and over thirty projectiles struck the country's power systems, describing such assaults as "strategic and deliberate" and against "critical infrastructure" as temperatures become colder.
The energy minister said Russia was "launching a major assault" and repair crews were striving to fix the damage.
A wave of strikes damaged energy infrastructure and civilian homes in the capital.
Multiple people hurt in the assaults on the city have been hospitalized, according to municipal representatives.
Regional authorities said the city came under heavy assaults overnight. A minor was killed and three other people were hurt.
The attacks follow nights of air raids in the territory, sections of which remain under the control of Moscow's military.
All of Ukraine is on alert for advanced weapon attacks, which are more difficult to spot.
Authorities told reporters that Moscow was intentionally trying to demolish the national power system, with strikes already impacting gas facilities.
Authorities confirmed technical personnel and government agencies were bracing for additional strikes.
