Throughout the evening, Russian aerial assaults have led to electricity outages in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were wounded while local people in eastern districts were plunged into darkness and dealt with disruption to water supplies, according to city officials.
Meanwhile, a minor was fatally injured in a different aerial attack in the southeastern region in the country's south-east, as reported by area administrators.
Moscow has escalated strikes on power infrastructure over the past few days, while officials has requested "real steps" from partner nations to increase pressure on Russia.

Several of the people injured in the assaults on the city have been transported for medical care, as confirmed by local officials.
Area administrators said the city came under heavy assaults throughout the evening. A minor was killed and three other people were hurt.
The attacks follow evenings of bombing campaigns in the region, portions of which are currently controlled by invading troops.
