Throughout the evening, Russian aerial assaults have caused electricity outages in multiple districts of the capital city, Kyiv.
A number of civilians were hurt while local people in eastern districts were plunged into darkness and faced interruptions to drinking water, per reports from city officials.
Meanwhile, a minor was killed in a different aerial attack in the southeastern region in the southeastern part, according to area administrators.
Moscow has increased strikes on power infrastructure over recent weeks, while the country's government has demanded "concrete actions" from partner nations to increase pressure on Moscow.
"What's needed is not superficial actions but strong steps - from the United States, European nations and the major economies - in delivering protection systems and enforcing restrictions," he wrote in a online statement.
Authorities reported that numerous aerial vehicles and over thirty missiles targeted Ukraine's energy infrastructure, labeling such strikes as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and repair crews were working to fix the damage.
A wave of strikes struck power facilities and apartment buildings in the capital.
Multiple people injured in the attacks on the city have been transported for medical care, per statements from municipal representatives.
Regional authorities said the city endured intense attacks overnight. A young boy lost their life and three other people were wounded.
The attacks come after evenings of bombing campaigns in the territory, parts of which remain under the control of Moscow's military.
The whole nation is in a state of readiness for sophisticated projectile assaults, which are tougher to identify.
Government officials told journalists that Russia was deliberately attempting to destroy the electrical infrastructure, with attacks already impacting fuel infrastructure.
He said technical personnel and authorities were bracing for additional strikes.
