During the night, Moscow's missile and drone strikes have led to blackouts in extensive areas of Ukraine's capital, Kyiv.
Nine people were injured while local people in the city's east were experienced blackouts and encountered interruptions to drinking water, according to city officials.
Meanwhile, a minor was killed in a different assault in the Zaporizhzhia region in the southern area, according to local officials.
Moscow has escalated assaults on power infrastructure over the past few days, while the country's government has requested "substantial measures" from partner nations to exert influence on Russia.
"The necessity is not symbolic gestures but firm measures - from the United States, the EU and the major economies - in supplying protection systems and applying restrictions," was stated in a public message.
Officials stated that numerous aerial vehicles and more than 30 projectiles attacked Ukraine's energy infrastructure, characterizing such assaults as "premeditated" and against "essential services" as temperatures become colder.
Energy officials said Moscow was "launching a major assault" and repair crews were working to repair systems.
A wave of strikes damaged electrical systems and residential structures in Kyiv.
Several of the people wounded in the strikes on the city have been hospitalized, as confirmed by municipal representatives.
Local officials said the metropolitan region came under intense attacks overnight. A young boy was killed and three other people were hurt.
The assaults come after evenings of aerial attacks in the territory, parts of which are currently controlled by Russian forces.
The whole nation is in a state of readiness for advanced weapon attacks, which are harder to identify.
Authorities told journalists that Russia was intentionally trying to destroy the national power system, with attacks already disrupting energy systems.
Officials stated energy workers and government agencies were anticipating further attacks.
