Overnight, Moscow's missile and drone strikes have caused electricity outages in large parts of Ukraine's capital, Kyiv.
Several individuals were injured while residents in the city's east were experienced blackouts and faced disruption to water supplies, according to city officials.
Simultaneously, a seven-year-old child was lost their life in a distinct assault in the southeastern region in the country's south-east, according to local officials.
Moscow has intensified attacks on energy facilities over the past few days, while Ukrainian leadership has called for "concrete actions" from allies to exert influence on Moscow.
"What's needed is not symbolic gestures but firm measures - from the United States, the EU and the major economies - in supplying defensive weapons and applying sanctions," mentioned in a online statement.
Authorities reported that hundreds of unmanned aircraft and over thirty missiles attacked Ukraine's energy infrastructure, labeling such attacks as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were working to repair systems.
A barrage of missiles struck electrical systems and civilian homes in Kyiv.
Multiple people hurt in the assaults on the city have been taken to hospital, as confirmed by city authorities.
Area administrators said the metropolitan region experienced intense attacks throughout the evening. A young boy died and several individuals were hurt.
The assaults follow evenings of air raids in the region, parts of which are occupied by Moscow's military.
The whole nation is under warning for hypersonic Kinzhal missile strikes, which are more difficult to detect.
Authorities told reporters that Moscow was intentionally trying to damage the country's energy grid, with attacks already disrupting energy systems.
Officials stated technical personnel and authorities were bracing for more assaults.
