Throughout the evening, Russian missile and drone strikes have resulted in blackouts in extensive areas of the capital city, Kyiv.
Nine people were hurt while inhabitants in the city's east were left without electricity and encountered interruptions to drinking water, according to local authorities.
At the same time, a seven-year-old child was fatally injured in a different assault in the Zaporizhzhia area in the southern area, as reported by local officials.
Russian forces has escalated strikes on power infrastructure over recent weeks, while Ukrainian leadership has demanded "substantial measures" from allies to apply pressure on Moscow.
"The necessity is not superficial actions but firm measures - from the US, European nations and the G7 - in delivering air defence systems and enforcing sanctions," was stated in a social media post.
Authorities reported that 450 drones and several dozen missiles targeted Ukraine's energy infrastructure, labeling such strikes as "premeditated" and against "everything that sustains normal life" as winter approaches.
Energy officials said Russia was "inflicting a massive strike" and technical staff were working to restore power.
A barrage of missiles struck electrical systems and residential structures in the capital.
Multiple people injured in the attacks on the city have been taken to hospital, per statements from city authorities.
Regional authorities said the city endured intense attacks throughout the evening. A young boy was killed and several individuals were wounded.
The attacks come after periods of air raids in the territory, portions of which are currently controlled by Moscow's military.
The whole nation is in a state of readiness for advanced weapon attacks, which are tougher to spot.
National leaders told journalists that Moscow was intentionally trying to damage the national power system, with assaults already affecting energy systems.
Officials stated technical personnel and government agencies were bracing for additional strikes.
