During the night, Moscow's missile and drone strikes have caused electricity outages in multiple districts of Ukraine's capital, Kyiv.
A number of civilians were hurt while local people in eastern neighborhoods were plunged into darkness and encountered problems to water supplies, according to municipal leaders.
At the same time, a minor was lost their life in a separate Russian drone strike in the Zaporizhzhia area in the southeastern part, as reported by local officials.
Russian forces has increased strikes on power infrastructure over the last fortnight, while Ukrainian leadership has requested "concrete actions" from partner nations to apply pressure on Moscow.
"What's needed is not symbolic gestures but firm measures - from the US, European nations and the Group of Seven - in supplying protection systems and applying restrictions," he wrote in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 projectiles struck the country's power systems, labeling such assaults as "strategic and deliberate" and against "critical infrastructure" as winter approaches.
Energy officials said Russia was "inflicting a massive strike" and technical staff were striving to fix the damage.
A series of attacks hit electrical systems and apartment buildings in Kyiv.
Five out of the nine people hurt in the strikes on the capital have been hospitalized, as confirmed by local officials.
Local officials said the city came under heavy assaults overnight. A young boy was killed and three other people were injured.
The assaults follow evenings of bombing campaigns in the region, parts of which are occupied by Russian forces.
The whole nation is in a state of readiness for sophisticated projectile assaults, which are more difficult to detect.
Government officials told the media that Moscow was deliberately attempting to damage the country's energy grid, with assaults already impacting energy systems.
He said technical personnel and officials were preparing for further attacks.
