During the night, Moscow's missile and drone strikes have caused electricity outages in multiple districts of Ukraine's capital, Kyiv.
Several individuals were wounded while inhabitants in eastern neighborhoods were left without electricity and dealt with problems to drinking water, according to city officials.
At the same time, a young boy was fatally injured in a separate assault in the southeastern region in the southern area, as reported by area administrators.
Moscow has increased strikes on power infrastructure over recent weeks, while the country's government has called for "concrete actions" from allies to increase pressure on Russia.
"What is required is not symbolic gestures but firm measures - from the US, Europe and the G7 - in supplying air defence systems and enforcing penalties," was stated in a public message.
Officials stated that numerous aerial vehicles and over thirty rockets struck Ukraine's energy infrastructure, describing such assaults as "strategic and deliberate" and against "essential services" as temperatures become colder.
Government representatives said Russia was "conducting extensive attacks" and repair crews were striving to restore power.
A barrage of missiles damaged electrical systems and residential structures in Kyiv.
Multiple people hurt in the strikes on the capital have been transported for medical care, per statements from city authorities.
Local officials said the city experienced intense attacks overnight. A young boy was killed and several individuals were wounded.
The assaults follow periods of aerial attacks in the area, portions of which remain under the control of Moscow's military.
The whole nation is on alert for advanced weapon attacks, which are more difficult to spot.
Government officials told journalists that Moscow was deliberately attempting to demolish the electrical infrastructure, with strikes already affecting energy systems.
Authorities confirmed technical personnel and government agencies were anticipating further attacks.
