During the night, Moscow's missile and drone strikes have led to electricity outages in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were wounded while residents in eastern neighborhoods were left without electricity and dealt with disruption to drinking water, per reports from municipal leaders.
At the same time, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia region in the southeastern part, as reported by local officials.
Moscow has intensified strikes on power infrastructure over recent weeks, while Ukrainian leadership has demanded "real steps" from allies to apply pressure on Russia.
"The necessity is not window dressing but firm measures - from the US, the EU and the Group of Seven - in providing air defence systems and enforcing penalties," he wrote in a public message.
Officials stated that 450 drones and several dozen missiles struck the country's power systems, describing such assaults as "strategic and deliberate" and against "essential services" as winter approaches.
Energy officials said Moscow was "inflicting a massive strike" and maintenance teams were laboring to repair systems.
A wave of strikes struck energy infrastructure and civilian homes in Kyiv.
Several of the people hurt in the assaults on the city have been taken to hospital, according to municipal representatives.
Area administrators said the metropolitan region experienced significant strikes overnight. A seven-year-old child lost their life and several individuals were wounded.
The attacks come after evenings of air raids in the territory, parts of which are occupied by Moscow's military.
The entire country is under warning for hypersonic Kinzhal missile strikes, which are harder to identify.
National leaders told the media that Russia was intentionally trying to damage the national power system, with attacks already affecting fuel infrastructure.
He said technical personnel and officials were bracing for more assaults.
