Overnight, Moscow's missile and drone strikes have led to power cuts in large parts of the capital city, the Ukrainian capital.
Nine people were wounded while residents in eastern neighborhoods were experienced blackouts and dealt with disruption to drinking water, according to municipal leaders.
Meanwhile, a minor was fatally injured in a separate assault in the southeastern region in the country's south-east, as reported by local officials.
Moscow has escalated attacks on energy facilities over the past few days, while Ukrainian leadership has demanded "concrete actions" from allies to apply pressure on Moscow.
"The necessity is not window dressing but firm measures - from the United States, European nations and the Group of Seven - in delivering defensive weapons and applying penalties," was stated in a social media post.
He said that hundreds of unmanned aircraft and more than 30 projectiles struck energy facilities, characterizing such attacks as "premeditated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Russia was "launching a major assault" and technical staff were working to restore power.
A series of attacks damaged electrical systems and residential structures in Kyiv.
Five out of the nine people hurt in the strikes on the capital have been taken to hospital, as confirmed by local officials.
Local officials said the city experienced intense attacks overnight. A minor was killed and several individuals were injured.
The strikes succeed periods of bombing campaigns in the territory, portions of which remain under the control of Moscow's military.
All of Ukraine is in a state of readiness for sophisticated projectile assaults, which are tougher to spot.
Authorities told journalists that Moscow was deliberately attempting to damage the country's energy grid, with strikes already disrupting gas facilities.
He said technical personnel and government agencies were preparing for further attacks.
