During the night, Russian missile and drone strikes have caused power cuts in large parts of Ukraine's capital, Kyiv.
Nine people were wounded while local people in eastern neighborhoods were left without electricity and dealt with interruptions to water systems, according to municipal leaders.
Simultaneously, a young boy was killed in a separate aerial attack in the southeastern region in the southern area, according to local officials.
Moscow has intensified assaults on electrical systems over recent weeks, while the country's government has demanded "concrete actions" from international partners to increase pressure on Russia.
"The necessity is not window dressing but decisive action - from the United States, European nations and the G7 - in supplying air defence systems and implementing penalties," was stated in a online statement.
He said that numerous aerial vehicles and more than 30 rockets targeted the country's power systems, characterizing such strikes as "premeditated" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "launching a major assault" and maintenance teams were striving to fix the damage.
A series of attacks hit energy infrastructure and residential structures in the capital.
Multiple people hurt in the strikes on the city have been hospitalized, as confirmed by city authorities.
Local officials said the urban area experienced significant strikes throughout the evening. A seven-year-old child lost their life and several individuals were hurt.
The strikes follow evenings of aerial attacks in the region, parts of which are occupied by Russian forces.
All of Ukraine is in a state of readiness for advanced weapon attacks, which are harder to identify.
National leaders told the media that Russia was purposely seeking to destroy the national power system, with strikes already disrupting fuel infrastructure.
Officials stated energy workers and authorities were bracing for further attacks.
