Overnight, Moscow's missile and drone strikes have led to blackouts in large parts of Ukraine's capital, Kyiv.
Nine people were wounded while residents in eastern districts were left without electricity and faced problems to water supplies, per reports from municipal leaders.
At the same time, a young boy was fatally injured in a separate assault in the southeastern region in the southeastern part, based on information from local officials.
Moscow has escalated assaults on energy facilities over the past few days, while officials has demanded "real steps" from partner nations to increase pressure on Russia.
"What is required is not superficial actions but decisive action - from the America, European nations and the major economies - in delivering defensive weapons and enforcing penalties," he wrote in a social media post.
He said that numerous aerial vehicles and more than 30 missiles targeted energy facilities, characterizing such assaults as "premeditated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Russia was "conducting extensive attacks" and technical staff were striving to repair systems.
A barrage of missiles struck energy infrastructure and civilian homes in the capital.
Five out of the nine people injured in the strikes on the city have been taken to hospital, per statements from local officials.
Local officials said the urban area experienced significant strikes during nighttime hours. A seven-year-old child lost their life and three other people were wounded.
The strikes succeed nights of bombing campaigns in the region, portions of which remain under the control of invading troops.
The whole nation is on alert for advanced weapon attacks, which are harder to identify.
Government officials told reporters that Russia was intentionally trying to damage the national power system, with assaults already affecting fuel infrastructure.
