Overnight, Moscow's missile and drone strikes have caused blackouts in multiple districts of Ukraine's capital, Kyiv.
A number of civilians were wounded while inhabitants in the city's east were left without electricity and faced interruptions to drinking water, according to municipal leaders.
Simultaneously, a young boy was lost their life in a distinct aerial attack in the Zaporizhzhia area in the country's south-east, as reported by regional authorities.
Moscow has increased assaults on electrical systems over the past few days, while Ukrainian leadership has requested "substantial measures" from international partners to increase pressure on Moscow.
"The necessity is not superficial actions but strong steps - from the United States, European nations and the G7 - in providing protection systems and implementing sanctions," he wrote in a public message.
He said that 450 drones and several dozen rockets attacked the country's power systems, labeling such assaults as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "conducting extensive attacks" and repair crews were working to fix the damage.
A wave of strikes struck energy infrastructure and residential structures in the capital.
Multiple people hurt in the assaults on the capital have been taken to hospital, per statements from municipal representatives.
Local officials said the metropolitan region came under significant strikes during nighttime hours. A seven-year-old child died and three other people were hurt.
The attacks follow periods of bombing campaigns in the region, sections of which are currently controlled by Russian forces.
All of Ukraine is on alert for sophisticated projectile assaults, which are more difficult to detect.
Authorities told the media that Russia was deliberately attempting to destroy the national power system, with attacks already affecting fuel infrastructure.
Authorities confirmed technical personnel and government agencies were bracing for additional strikes.
