Throughout the evening, Moscow's missile and drone strikes have resulted in electricity outages in large parts of the capital city, Kyiv.
Several individuals were injured while local people in eastern neighborhoods were plunged into darkness and dealt with disruption to drinking water, according to municipal leaders.
At the same time, a young boy was fatally injured in a separate assault in the southeastern region in the country's south-east, as reported by local officials.
Moscow has increased strikes on energy facilities over recent weeks, while Ukrainian leadership has requested "substantial measures" from international partners to exert influence on Russia.
"What's needed is not symbolic gestures but decisive action - from the United States, the EU and the major economies - in delivering protection systems and implementing sanctions," he wrote in a social media post.
He said that numerous aerial vehicles and several dozen projectiles struck energy facilities, labeling such strikes as "premeditated" and against "essential services" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and technical staff were striving to fix the damage.
A barrage of missiles hit power facilities and apartment buildings in the capital.
Five out of the nine people hurt in the assaults on the capital have been hospitalized, as confirmed by municipal representatives.
Local officials said the metropolitan region experienced intense attacks overnight. A young boy lost their life and multiple civilians were wounded.
The attacks follow nights of air raids in the area, sections of which are currently controlled by invading troops.
All of Ukraine is in a state of readiness for sophisticated projectile assaults, which are more difficult to identify.
Authorities told the media that Moscow was purposely seeking to destroy the electrical infrastructure, with attacks already impacting energy systems.
Authorities confirmed energy workers and authorities were bracing for additional strikes.
