Throughout the evening, Russian aerial assaults have resulted in blackouts in large parts of Ukraine's capital, Kyiv.
Several individuals were wounded while local people in the city's east were left without electricity and faced problems to drinking water, as stated by local authorities.
At the same time, a young boy was killed in a different assault in the Zaporizhzhia region in the southeastern part, based on information from local officials.
Moscow has escalated assaults on electrical systems over the past few days, while the country's government has called for "substantial measures" from international partners to exert influence on Russia.
"What's needed is not superficial actions but firm measures - from the America, Europe and the G7 - in providing air defence systems and applying sanctions," was stated in a social media post.
Officials stated that hundreds of unmanned aircraft and several dozen missiles attacked the country's power systems, labeling such strikes as "premeditated" and against "critical infrastructure" as temperatures become colder.
The energy minister said Moscow was "inflicting a massive strike" and technical staff were striving to restore power.
A series of attacks struck electrical systems and civilian homes in the capital.
Several of the people wounded in the assaults on the city have been taken to hospital, as confirmed by city authorities.
Regional authorities said the metropolitan region came under intense attacks throughout the evening. A minor was killed and three other people were wounded.
The attacks follow periods of air raids in the area, parts of which are occupied by Moscow's military.
The whole nation is under warning for advanced weapon attacks, which are tougher to spot.
Government officials told reporters that Moscow was purposely seeking to demolish the national power system, with assaults already impacting energy systems.
Authorities confirmed technical personnel and government agencies were bracing for further attacks.
