Throughout the evening, Moscow's missile and drone strikes have resulted in power cuts in multiple districts of Ukraine's capital, Kyiv.
Nine people were wounded while residents in the city's east were plunged into darkness and dealt with problems to water systems, according to city officials.
At the same time, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia region in the country's south-east, according to regional authorities.
Moscow has escalated strikes on electrical systems over the last fortnight, while Ukrainian leadership has called for "substantial measures" from allies to exert influence on Russia.
"What is required is not window dressing but firm measures - from the United States, the EU and the major economies - in providing defensive weapons and enforcing restrictions," mentioned in a social media post.
Officials stated that hundreds of unmanned aircraft and several dozen missiles struck Ukraine's energy infrastructure, describing such attacks as "strategic and deliberate" and against "critical infrastructure" as winter approaches.
Energy officials said Moscow was "launching a major assault" and repair crews were working to repair systems.
A wave of strikes hit electrical systems and residential structures in the capital.
Multiple people hurt in the attacks on the capital have been hospitalized, as confirmed by local officials.
Regional authorities said the city experienced intense attacks throughout the evening. A young boy died and three other people were hurt.
The attacks follow nights of air raids in the territory, parts of which are currently controlled by invading troops.
The whole nation is under warning for advanced weapon attacks, which are harder to spot.
Authorities told journalists that Moscow was deliberately attempting to damage the electrical infrastructure, with attacks already affecting fuel infrastructure.
Officials stated utility staff and officials were bracing for more assaults.
