Overnight, Russian missile and drone strikes have resulted in power cuts in multiple districts of the capital city, Kyiv.
A number of civilians were hurt while residents in eastern districts were experienced blackouts and encountered problems to water systems, according to city officials.
At the same time, a seven-year-old child was fatally injured in a different assault in the Zaporizhzhia region in the country's south-east, as reported by area administrators.
Moscow has intensified attacks on energy facilities over the past few days, while Ukrainian leadership has demanded "substantial measures" from international partners to apply pressure on Moscow.

Officials stated that 450 drones and several dozen missiles attacked Ukraine's energy infrastructure, describing such attacks as "strategic and deliberate" and against "everything that sustains normal life" as temperatures become colder.
Energy officials said Russia was "launching a major assault" and repair crews were laboring to repair systems.
A series of attacks hit electrical systems and apartment buildings in the capital.
Multiple people hurt in the attacks on the city have been transported for medical care, according to municipal representatives.
Local officials said the metropolitan region experienced intense attacks during nighttime hours. A seven-year-old child died and multiple civilians were injured.
The assaults succeed periods of bombing campaigns in the territory, parts of which are occupied by invading troops.
The entire country is on alert for sophisticated projectile assaults, which are harder to detect.
