Overnight, Moscow's aerial assaults have led to power cuts in extensive areas of the capital city, Kyiv.
A number of civilians were hurt while residents in eastern neighborhoods were left without electricity and faced problems to water supplies, per reports from municipal leaders.
At the same time, a minor was fatally injured in a separate assault in the Zaporizhzhia area in the country's south-east, based on information from regional authorities.
Moscow has intensified assaults on energy facilities over the last fortnight, while officials has requested "substantial measures" from international partners to increase pressure on Moscow.
"The necessity is not superficial actions but firm measures - from the United States, European nations and the major economies - in providing air defence systems and applying restrictions," was stated in a social media post.
Authorities reported that hundreds of unmanned aircraft and over thirty rockets targeted Ukraine's energy infrastructure, labeling such attacks as "strategic and deliberate" and against "critical infrastructure" as temperatures become colder.
Government representatives said Russia was "launching a major assault" and technical staff were striving to repair systems.
A barrage of missiles hit energy infrastructure and civilian homes in Kyiv.
Several of the people injured in the attacks on the city have been taken to hospital, per statements from municipal representatives.
Regional authorities said the city endured heavy assaults overnight. A seven-year-old child was killed and three other people were hurt.
The attacks follow periods of air raids in the area, parts of which are occupied by Moscow's military.
The entire country is on alert for advanced weapon attacks, which are harder to detect.
Government officials told reporters that Moscow was intentionally trying to demolish the electrical infrastructure, with assaults already impacting energy systems.
Authorities confirmed energy workers and officials were preparing for additional strikes.
