Throughout the evening, Moscow's missile and drone strikes have resulted in blackouts in large parts of Ukraine's capital, Kyiv.
Several individuals were hurt while residents in eastern neighborhoods were plunged into darkness and dealt with interruptions to water supplies, according to city officials.
Simultaneously, a seven-year-old child was killed in a different assault in the southeastern region in the country's south-east, as reported by local officials.
Moscow has increased strikes on electrical systems over the last fortnight, while officials has called for "real steps" from international partners to exert influence on Russia.
"The necessity is not superficial actions but strong steps - from the US, Europe and the G7 - in delivering protection systems and implementing penalties," he wrote in a public message.
Officials stated that 450 drones and several dozen projectiles targeted Ukraine's energy infrastructure, describing such strikes as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Russia was "launching a major assault" and technical staff were laboring to restore power.
A barrage of missiles damaged power facilities and apartment buildings in Kyiv.
Five out of the nine people hurt in the attacks on the capital have been taken to hospital, according to local officials.
Regional authorities said the metropolitan region came under significant strikes overnight. A seven-year-old child lost their life and multiple civilians were injured.
The attacks come after evenings of aerial attacks in the territory, parts of which are currently controlled by invading troops.
The entire country is on alert for sophisticated projectile assaults, which are tougher to identify.
National leaders told the media that Russia was deliberately attempting to destroy the country's energy grid, with assaults already impacting gas facilities.
Authorities confirmed utility staff and authorities were anticipating further attacks.
