During the night, Moscow's missile and drone strikes have resulted in blackouts in multiple districts of Ukraine's capital, Kyiv.
Nine people were injured while residents in the city's east were plunged into darkness and faced interruptions to drinking water, per reports from municipal leaders.
Meanwhile, a young boy was killed in a different assault in the Zaporizhzhia area in the southeastern part, according to local officials.
Moscow has escalated strikes on energy facilities over the past few days, while Ukrainian leadership has called for "substantial measures" from allies to exert influence on Moscow.
"The necessity is not window dressing but firm measures - from the America, European nations and the major economies - in supplying defensive weapons and enforcing restrictions," mentioned in a public message.
Authorities reported that 450 drones and several dozen missiles attacked energy facilities, labeling such assaults as "strategic and deliberate" and against "essential services" as the weather cools.
The energy minister said Russia was "conducting extensive attacks" and technical staff were working to restore power.
A series of attacks struck power facilities and apartment buildings in the capital.
Several of the people injured in the assaults on the city have been hospitalized, according to city authorities.
Area administrators said the city endured significant strikes during nighttime hours. A young boy died and several individuals were hurt.
The strikes succeed nights of aerial attacks in the area, portions of which remain under the control of Moscow's military.
The whole nation is under warning for hypersonic Kinzhal missile strikes, which are harder to identify.
Authorities told journalists that Moscow was deliberately attempting to demolish the electrical infrastructure, with strikes already impacting fuel infrastructure.
Officials stated technical personnel and officials were preparing for further attacks.
