Throughout the evening, Russian aerial assaults have resulted in power cuts in multiple districts of Ukraine's capital, Kyiv.
Nine people were wounded while local people in the city's east were plunged into darkness and faced disruption to water supplies, according to city officials.
Simultaneously, a young boy was lost their life in a different assault in the Zaporizhzhia region in the country's south-east, as reported by regional authorities.
Moscow has increased strikes on power infrastructure over recent weeks, while Ukrainian leadership has called for "substantial measures" from international partners to increase pressure on Russia.
"What is required is not symbolic gestures but strong steps - from the United States, Europe and the G7 - in supplying protection systems and implementing sanctions," he wrote in a online statement.
Officials stated that numerous aerial vehicles and more than 30 projectiles targeted the country's power systems, labeling such attacks as "cynical and calculated" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "launching a major assault" and technical staff were striving to restore power.
A wave of strikes struck power facilities and civilian homes in Kyiv.
Several of the people injured in the assaults on the city have been hospitalized, per statements from municipal representatives.
Local officials said the metropolitan region experienced intense attacks overnight. A seven-year-old child died and three other people were hurt.
The assaults succeed evenings of air raids in the area, parts of which remain under the control of invading troops.
The whole nation is in a state of readiness for hypersonic Kinzhal missile strikes, which are harder to spot.
Government officials told reporters that Moscow was deliberately attempting to damage the electrical infrastructure, with assaults already affecting energy systems.
Officials stated utility staff and authorities were preparing for additional strikes.
