Throughout the evening, Russian aerial assaults have resulted in electricity outages in multiple districts of the capital city, the Ukrainian capital.
A number of civilians were wounded while residents in eastern neighborhoods were plunged into darkness and encountered problems to water systems, according to municipal leaders.
Meanwhile, a young boy was fatally injured in a separate assault in the Zaporizhzhia region in the country's south-east, as reported by regional authorities.
Moscow has increased assaults on power infrastructure over recent weeks, while officials has called for "substantial measures" from international partners to apply pressure on Russia.

He said that 450 drones and more than 30 rockets targeted Ukraine's energy infrastructure, characterizing such assaults as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.

A barrage of missiles struck energy infrastructure and civilian homes in Kyiv.
Five out of the nine people injured in the strikes on the city have been taken to hospital, as confirmed by city authorities.
