Overnight, Moscow's missile and drone strikes have caused electricity outages in multiple districts of Ukraine's capital, Kyiv.
Nine people were wounded while residents in the city's east were experienced blackouts and faced problems to water supplies, per reports from city officials.
At the same time, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia region in the country's south-east, based on information from local officials.
Russian forces has increased attacks on power infrastructure over the past few days, while Ukrainian leadership has requested "concrete actions" from allies to apply pressure on Moscow.
"The necessity is not symbolic gestures but strong steps - from the United States, the EU and the G7 - in supplying protection systems and applying penalties," he wrote in a social media post.
Authorities reported that numerous aerial vehicles and several dozen missiles struck Ukraine's energy infrastructure, characterizing such assaults as "strategic and deliberate" and against "essential services" as temperatures become colder.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were striving to fix the damage.
A barrage of missiles damaged energy infrastructure and civilian homes in the capital.
Five out of the nine people wounded in the assaults on the city have been hospitalized, according to municipal representatives.
Area administrators said the urban area came under heavy assaults overnight. A minor lost their life and multiple civilians were wounded.
The strikes follow periods of aerial attacks in the area, sections of which are occupied by Russian forces.
The whole nation is in a state of readiness for hypersonic Kinzhal missile strikes, which are tougher to identify.
Authorities told reporters that Russia was deliberately attempting to demolish the national power system, with strikes already impacting fuel infrastructure.
Officials stated utility staff and authorities were bracing for more assaults.
