Throughout the evening, Russian aerial assaults have led to blackouts in large parts of Ukraine's capital, Kyiv.
Several individuals were wounded while inhabitants in eastern districts were experienced blackouts and dealt with disruption to water systems, as stated by local authorities.
Meanwhile, a young boy was fatally injured in a distinct aerial attack in the Zaporizhzhia area in the country's south-east, according to local officials.
Moscow has intensified assaults on energy facilities over recent weeks, while the country's government has demanded "concrete actions" from international partners to apply pressure on Russia.
"The necessity is not symbolic gestures but strong steps - from the US, Europe and the Group of Seven - in delivering defensive weapons and enforcing penalties," he wrote in a public message.
Officials stated that numerous aerial vehicles and over thirty projectiles targeted Ukraine's energy infrastructure, describing such assaults as "cynical and calculated" and against "essential services" as temperatures become colder.
Government representatives said Russia was "inflicting a massive strike" and repair crews were working to fix the damage.
A wave of strikes struck electrical systems and apartment buildings in the capital.
Several of the people wounded in the attacks on the capital have been transported for medical care, per statements from city authorities.
Area administrators said the urban area experienced heavy assaults overnight. A seven-year-old child lost their life and several individuals were injured.
The strikes come after periods of air raids in the territory, parts of which remain under the control of Russian forces.
The entire country is on alert for sophisticated projectile assaults, which are harder to detect.
Government officials told reporters that Moscow was purposely seeking to damage the country's energy grid, with attacks already affecting energy systems.
Officials stated utility staff and government agencies were preparing for more assaults.
