Overnight, Russian missile and drone strikes have caused power cuts in large parts of the capital city, the Ukrainian capital.
A number of civilians were hurt while inhabitants in eastern neighborhoods were plunged into darkness and dealt with problems to drinking water, according to local authorities.
At the same time, a minor was killed in a different Russian drone strike in the Zaporizhzhia area in the country's south-east, according to local officials.
Moscow has increased strikes on power infrastructure over recent weeks, while Ukrainian leadership has called for "substantial measures" from partner nations to apply pressure on Moscow.
"What is required is not window dressing but firm measures - from the America, Europe and the G7 - in supplying air defence systems and implementing sanctions," he wrote in a online statement.
Officials stated that 450 drones and several dozen projectiles struck the country's power systems, labeling such strikes as "strategic and deliberate" and against "critical infrastructure" as temperatures become colder.
Energy officials said Moscow was "inflicting a massive strike" and technical staff were laboring to restore power.
A wave of strikes damaged electrical systems and apartment buildings in the capital.
Several of the people injured in the strikes on the capital have been transported for medical care, according to city authorities.
Local officials said the urban area endured significant strikes during nighttime hours. A young boy died and multiple civilians were injured.
The assaults follow periods of bombing campaigns in the territory, sections of which remain under the control of Russian forces.
The entire country is on alert for sophisticated projectile assaults, which are more difficult to identify.
National leaders told journalists that Russia was intentionally trying to damage the national power system, with attacks already impacting energy systems.
Officials stated energy workers and officials were preparing for more assaults.
