Overnight, Moscow's aerial assaults have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
Nine people were wounded while local people in the city's east were experienced blackouts and encountered interruptions to water systems, according to municipal leaders.
At the same time, a minor was fatally injured in a distinct aerial attack in the Zaporizhzhia region in the southeastern part, as reported by regional authorities.
Moscow has intensified attacks on energy facilities over the last fortnight, while Ukrainian leadership has demanded "real steps" from international partners to exert influence on Russia.
"What is required is not symbolic gestures but decisive action - from the US, the EU and the major economies - in delivering air defence systems and implementing restrictions," he wrote in a social media post.
Authorities reported that numerous aerial vehicles and more than 30 rockets struck the country's power systems, labeling such attacks as "cynical and calculated" and against "critical infrastructure" as winter approaches.
Government representatives said Moscow was "inflicting a massive strike" and repair crews were laboring to restore power.
A barrage of missiles damaged electrical systems and civilian homes in Kyiv.
Several of the people wounded in the assaults on the capital have been hospitalized, as confirmed by municipal representatives.
Regional authorities said the metropolitan region came under heavy assaults overnight. A seven-year-old child died and three other people were injured.
The attacks succeed periods of bombing campaigns in the area, sections of which are occupied by Moscow's military.
The whole nation is in a state of readiness for hypersonic Kinzhal missile strikes, which are tougher to detect.
Authorities told reporters that Moscow was deliberately attempting to demolish the country's energy grid, with attacks already affecting fuel infrastructure.
Officials stated utility staff and officials were preparing for more assaults.
