Overnight, Moscow's missile and drone strikes have caused power cuts in multiple districts of the capital city, Kyiv.
A number of civilians were hurt while inhabitants in eastern neighborhoods were plunged into darkness and encountered disruption to water systems, per reports from city officials.
Simultaneously, a young boy was fatally injured in a different assault in the Zaporizhzhia area in the country's south-east, as reported by area administrators.
Moscow has intensified assaults on electrical systems over the past few days, while Ukrainian leadership has requested "real steps" from allies to apply pressure on Russia.
"The necessity is not superficial actions but strong steps - from the America, the EU and the Group of Seven - in delivering defensive weapons and implementing sanctions," was stated in a public message.
Authorities reported that 450 drones and several dozen missiles targeted energy facilities, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Russia was "inflicting a massive strike" and technical staff were laboring to restore power.
A wave of strikes struck electrical systems and residential structures in the capital.
Multiple people hurt in the strikes on the capital have been hospitalized, according to municipal representatives.
Area administrators said the urban area experienced heavy assaults throughout the evening. A minor died and three other people were wounded.
The attacks come after periods of bombing campaigns in the region, sections of which remain under the control of invading troops.
All of Ukraine is on alert for advanced weapon attacks, which are tougher to identify.
National leaders told journalists that Moscow was intentionally trying to demolish the electrical infrastructure, with attacks already affecting gas facilities.
Officials stated energy workers and government agencies were preparing for additional strikes.
