Throughout the evening, Russian missile and drone strikes have caused power cuts in multiple districts of Ukraine's capital, Kyiv.
Several individuals were hurt while local people in eastern neighborhoods were plunged into darkness and dealt with problems to water systems, as stated by local authorities.
At the same time, a young boy was killed in a different Russian drone strike in the Zaporizhzhia area in the country's south-east, according to regional authorities.
Moscow has increased attacks on power infrastructure over the last fortnight, while the country's government has called for "substantial measures" from partner nations to apply pressure on Moscow.
"The necessity is not symbolic gestures but decisive action - from the United States, European nations and the G7 - in supplying defensive weapons and implementing restrictions," was stated in a social media post.
Officials stated that hundreds of unmanned aircraft and more than 30 missiles targeted Ukraine's energy infrastructure, labeling such strikes as "premeditated" and against "critical infrastructure" as temperatures become colder.
Government representatives said Russia was "inflicting a massive strike" and maintenance teams were laboring to fix the damage.
A series of attacks struck electrical systems and residential structures in Kyiv.
Multiple people hurt in the strikes on the city have been transported for medical care, according to city authorities.
Regional authorities said the city experienced intense attacks overnight. A seven-year-old child died and three other people were hurt.
The attacks come after nights of aerial attacks in the area, parts of which are occupied by invading troops.
The whole nation is under warning for advanced weapon attacks, which are tougher to identify.
Government officials told journalists that Moscow was intentionally trying to damage the country's energy grid, with strikes already disrupting energy systems.
He said technical personnel and officials were bracing for additional strikes.
