Overnight, Russian missile and drone strikes have caused electricity outages in extensive areas of the capital city, Kyiv.
A number of civilians were wounded while inhabitants in the city's east were plunged into darkness and dealt with interruptions to drinking water, according to local authorities.
At the same time, a seven-year-old child was killed in a different assault in the Zaporizhzhia region in the southern area, as reported by area administrators.
Moscow has escalated strikes on energy facilities over recent weeks, while Ukrainian leadership has called for "real steps" from partner nations to increase pressure on Russia.
"The necessity is not window dressing but strong steps - from the United States, Europe and the G7 - in delivering air defence systems and enforcing penalties," he wrote in a public message.
Officials stated that numerous aerial vehicles and several dozen rockets attacked the country's power systems, describing such assaults as "premeditated" and against "critical infrastructure" as the weather cools.
Government representatives said Moscow was "launching a major assault" and repair crews were striving to repair systems.
A barrage of missiles hit power facilities and civilian homes in Kyiv.
Several of the people hurt in the strikes on the capital have been taken to hospital, according to city authorities.
Local officials said the urban area experienced heavy assaults during nighttime hours. A young boy died and several individuals were injured.
The attacks succeed evenings of air raids in the region, sections of which are currently controlled by Moscow's military.
All of Ukraine is in a state of readiness for advanced weapon attacks, which are tougher to spot.
National leaders told the media that Moscow was purposely seeking to damage the electrical infrastructure, with attacks already impacting gas facilities.
He said utility staff and authorities were preparing for further attacks.
