Overnight, Moscow's missile and drone strikes have caused electricity outages in multiple districts of the capital city, the Ukrainian capital.
A number of civilians were hurt while local people in eastern districts were experienced blackouts and dealt with interruptions to water systems, per reports from municipal leaders.
Meanwhile, a young boy was killed in a separate assault in the Zaporizhzhia area in the country's south-east, according to local officials.
Moscow has increased attacks on electrical systems over the last fortnight, while the country's government has requested "real steps" from international partners to exert influence on Moscow.
"What is required is not symbolic gestures but firm measures - from the America, European nations and the Group of Seven - in providing air defence systems and applying penalties," he wrote in a online statement.
Officials stated that hundreds of unmanned aircraft and over thirty projectiles attacked Ukraine's energy infrastructure, characterizing such assaults as "cynical and calculated" and against "essential services" as temperatures become colder.
Government representatives said Russia was "launching a major assault" and technical staff were working to repair systems.
A wave of strikes struck electrical systems and civilian homes in the capital.
Several of the people hurt in the strikes on the city have been hospitalized, per statements from city authorities.
Local officials said the urban area endured significant strikes during nighttime hours. A seven-year-old child died and three other people were wounded.
The assaults follow evenings of bombing campaigns in the territory, parts of which are occupied by invading troops.
All of Ukraine is in a state of readiness for sophisticated projectile assaults, which are tougher to detect.
Government officials told the media that Russia was deliberately attempting to demolish the country's energy grid, with strikes already affecting gas facilities.
He said utility staff and government agencies were preparing for further attacks.
