Overnight, Moscow's missile and drone strikes have caused electricity outages in multiple districts of the capital city, the Ukrainian capital.
Nine people were injured while local people in eastern districts were experienced blackouts and faced problems to water supplies, according to city officials.
Meanwhile, a minor was lost their life in a separate assault in the Zaporizhzhia area in the southeastern part, as reported by regional authorities.
Moscow has increased strikes on energy facilities over the past few days, while officials has called for "concrete actions" from allies to exert influence on Moscow.
"The necessity is not superficial actions but firm measures - from the US, the EU and the major economies - in supplying air defence systems and implementing penalties," he wrote in a online statement.
He said that hundreds of unmanned aircraft and over thirty missiles attacked Ukraine's energy infrastructure, describing such strikes as "cynical and calculated" and against "essential services" as temperatures become colder.
Government representatives said Russia was "inflicting a massive strike" and technical staff were working to fix the damage.
A wave of strikes hit power facilities and residential structures in the capital.
Five out of the nine people wounded in the assaults on the city have been transported for medical care, according to municipal representatives.
Regional authorities said the metropolitan region experienced significant strikes during nighttime hours. A young boy lost their life and multiple civilians were injured.
The strikes succeed evenings of aerial attacks in the region, parts of which remain under the control of Russian forces.
The whole nation is under warning for advanced weapon attacks, which are tougher to detect.
National leaders told journalists that Moscow was deliberately attempting to damage the electrical infrastructure, with assaults already disrupting gas facilities.
Authorities confirmed technical personnel and government agencies were bracing for more assaults.
