During the night, Russian aerial assaults have led to power cuts in large parts of the capital city, Kyiv.
Nine people were injured while local people in the city's east were plunged into darkness and faced problems to water supplies, according to local authorities.
Meanwhile, a young boy was killed in a separate Russian drone strike in the Zaporizhzhia region in the southeastern part, based on information from local officials.
Moscow has escalated assaults on energy facilities over recent weeks, while the country's government has demanded "real steps" from international partners to increase pressure on Moscow.
"The necessity is not superficial actions but decisive action - from the United States, European nations and the Group of Seven - in delivering defensive weapons and implementing restrictions," was stated in a social media post.
Officials stated that hundreds of unmanned aircraft and over thirty projectiles struck Ukraine's energy infrastructure, labeling such strikes as "premeditated" and against "everything that sustains normal life" as the weather cools.
Government representatives said Moscow was "launching a major assault" and technical staff were laboring to restore power.
A series of attacks hit energy infrastructure and civilian homes in Kyiv.
Several of the people hurt in the attacks on the capital have been transported for medical care, as confirmed by local officials.
Local officials said the city endured significant strikes overnight. A young boy died and several individuals were injured.
The assaults follow evenings of air raids in the territory, parts of which are occupied by invading troops.
The whole nation is under warning for hypersonic Kinzhal missile strikes, which are tougher to spot.
Government officials told reporters that Moscow was deliberately attempting to demolish the national power system, with attacks already disrupting fuel infrastructure.
Authorities confirmed energy workers and authorities were anticipating additional strikes.
