Overnight, Moscow's missile and drone strikes have led to blackouts in large parts of Ukraine's capital, Kyiv.
Nine people were injured while inhabitants in eastern neighborhoods were left without electricity and faced disruption to water supplies, per reports from local authorities.
Simultaneously, a minor was killed in a distinct Russian drone strike in the southeastern region in the southeastern part, according to regional authorities.
Moscow has increased attacks on power infrastructure over the last fortnight, while the country's government has requested "concrete actions" 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 delivering air defence systems and applying sanctions," he wrote in a public message.
Authorities reported that numerous aerial vehicles and more than 30 missiles targeted the country's power systems, describing such attacks as "premeditated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Russia was "launching a major assault" and maintenance teams were striving to restore power.
A wave of strikes damaged electrical systems and apartment buildings in Kyiv.
Several of the people wounded in the attacks on the city have been transported for medical care, as confirmed by city authorities.
Local officials said the urban area came under intense attacks overnight. A young boy was killed and several individuals were injured.
The assaults succeed nights of aerial attacks in the area, portions of which are currently controlled by Russian forces.
The entire country is in a state of readiness for advanced weapon attacks, which are tougher to identify.
National leaders told reporters that Moscow was purposely seeking to demolish the national power system, with attacks already disrupting energy systems.
Authorities confirmed utility staff and officials were bracing for further attacks.
