During the night, Moscow's missile and drone strikes have caused power cuts in multiple districts of the capital city, Kyiv.
A number of civilians were wounded while residents in the city's east were left without electricity and encountered disruption to drinking water, as stated by city officials.
Simultaneously, a minor was fatally injured in a different assault in the southeastern region in the country's south-east, based on information from area administrators.
Moscow has intensified attacks on energy facilities over the past few days, while the country's government has called for "concrete actions" from partner nations to increase pressure on Moscow.
"What is required is not window dressing but decisive action - from the United States, the EU and the major economies - in providing defensive weapons and implementing penalties," he wrote in a social media post.
He said that 450 drones and several dozen projectiles attacked Ukraine's energy infrastructure, labeling such strikes as "cynical and calculated" and against "critical infrastructure" as the weather cools.
Energy officials said Moscow was "launching a major assault" and repair crews were working to repair systems.
A barrage of missiles hit electrical systems and civilian homes in the capital.
Multiple people hurt in the assaults on the city have been transported for medical care, per statements from local officials.
Regional authorities said the metropolitan region came under significant strikes during nighttime hours. A minor died and three other people were injured.
The attacks follow periods of bombing campaigns in the region, portions of which are currently controlled by Russian forces.
The whole nation is under warning for hypersonic Kinzhal missile strikes, which are harder to identify.
Government officials told journalists that Russia was intentionally trying to damage the country's energy grid, with attacks already disrupting gas facilities.
Authorities confirmed energy workers and officials were anticipating more assaults.
