During the night, Moscow's missile and drone strikes have caused blackouts in extensive areas of Ukraine's capital, Kyiv.
Nine people were hurt while local people in the city's east were left without electricity and dealt with problems to water supplies, per reports from city officials.
Meanwhile, a minor was killed in a different assault in the Zaporizhzhia region in the southeastern part, as reported by local officials.
Moscow has escalated assaults on electrical systems over recent weeks, while Ukrainian leadership has requested "real steps" from international partners to exert influence on Moscow.
"The necessity is not window dressing but decisive action - from the United States, European nations and the G7 - in supplying protection systems and applying penalties," mentioned in a public message.
Officials stated that hundreds of unmanned aircraft and several dozen missiles targeted Ukraine's energy infrastructure, characterizing such attacks as "premeditated" and against "essential services" as the weather cools.
The energy minister said Russia was "launching a major assault" and maintenance teams were striving to fix the damage.
A series of attacks struck energy infrastructure and civilian homes in Kyiv.
Multiple people injured in the attacks on the city have been taken to hospital, according to municipal representatives.
Area administrators said the city experienced intense attacks during nighttime hours. A seven-year-old child died and multiple civilians were wounded.
The assaults follow nights of bombing campaigns in the territory, portions of which remain under the control of Russian forces.
The whole nation is under warning for advanced weapon attacks, which are harder to detect.
National leaders told the media that Russia was intentionally trying to destroy the national power system, with strikes already disrupting gas facilities.
Authorities confirmed energy workers and officials were anticipating more assaults.
