Overnight, 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 local people in eastern neighborhoods were left without electricity and faced interruptions to drinking water, per reports from local authorities.
Meanwhile, a seven-year-old child was killed in a different assault in the Zaporizhzhia region in the country's south-east, based on information from local officials.
Moscow has intensified strikes on electrical systems over the past few days, while officials has demanded "substantial measures" from partner nations to apply pressure on Russia.
"The necessity is not symbolic gestures but decisive action - from the America, Europe and the G7 - in delivering defensive weapons and enforcing penalties," he wrote in a public message.
Officials stated that numerous aerial vehicles and more than 30 rockets attacked energy facilities, describing such attacks as "strategic and deliberate" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and repair crews were striving to restore power.
A wave of strikes hit power facilities and residential structures in Kyiv.
Five out of the nine people wounded in the strikes on the capital have been transported for medical care, according to local officials.
Regional authorities said the urban area endured heavy assaults overnight. A minor died and several individuals were wounded.
The assaults succeed nights of bombing campaigns in the area, parts of which are occupied by Moscow's military.
The entire country is under warning for advanced weapon attacks, which are harder to detect.
Authorities told the media that Moscow was intentionally trying to damage the electrical infrastructure, with assaults already impacting fuel infrastructure.
Officials stated technical personnel and government agencies were bracing for additional strikes.
