Throughout the evening, Moscow's missile and drone strikes have resulted in power cuts in large parts of Ukraine's capital, Kyiv.
A number of civilians were injured while local people in eastern districts were left without electricity and faced interruptions to water supplies, according to local authorities.
Meanwhile, a minor was lost their life in a separate assault in the Zaporizhzhia area in the country's south-east, according to area administrators.
Moscow has intensified strikes on electrical systems over recent weeks, while officials has demanded "real steps" from international partners to increase pressure on Moscow.
"The necessity is not symbolic gestures but strong steps - from the America, Europe and the major economies - in providing protection systems and applying sanctions," was stated in a public message.
Officials stated that numerous aerial vehicles and more than 30 rockets attacked energy facilities, describing such assaults as "strategic and deliberate" and against "everything that sustains normal life" as the weather cools.
Government representatives said Russia was "inflicting a massive strike" and repair crews were laboring to restore power.
A series of attacks struck energy infrastructure and civilian homes in the capital.
Several of the people wounded in the strikes on the city have been transported for medical care, according to local officials.
Area administrators said the city experienced significant strikes throughout the evening. A minor died and several individuals were injured.
The assaults follow nights of bombing campaigns in the territory, parts of which are occupied by Russian forces.
The entire country is under warning for advanced weapon attacks, which are tougher to spot.
Government officials told journalists that Moscow was purposely seeking to destroy the national power system, with strikes already impacting fuel infrastructure.
He said technical personnel and government agencies were anticipating additional strikes.
