During the night, Russian missile and drone strikes have caused power cuts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were wounded while local people in eastern districts were experienced blackouts and dealt with disruption to drinking water, according to municipal leaders.
At the same time, a young boy was fatally injured in a distinct assault in the southeastern region in the country's south-east, based on information from area administrators.
Moscow has intensified strikes on energy facilities over the past few days, while the country's government has requested "substantial measures" from partner nations to increase pressure on Moscow.
"What's needed is not superficial actions but strong steps - from the US, the EU and the major economies - in supplying air defence systems and implementing restrictions," he wrote in a social media post.
He said that 450 drones and over thirty rockets struck the country's power systems, describing such strikes as "premeditated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Moscow was "launching a major assault" and technical staff were laboring to repair systems.
A barrage of missiles hit power facilities and residential structures in the capital.
Five out of the nine people hurt in the strikes on the city have been transported for medical care, per statements from local officials.
Local officials said the metropolitan region experienced intense attacks during nighttime hours. A minor lost their life and multiple civilians were hurt.
The strikes come after nights of air raids in the territory, parts of which are currently controlled by invading troops.
The entire country is under warning for sophisticated projectile assaults, which are tougher to detect.
National leaders told the media that Russia was intentionally trying to damage the electrical infrastructure, with attacks already disrupting gas facilities.
Authorities confirmed energy workers and government agencies were anticipating further attacks.
