Overnight, Russian aerial assaults have led to power cuts in extensive areas of the capital city, Kyiv.
A number of civilians were wounded while inhabitants in the city's east were left without electricity and encountered disruption to drinking water, per reports from municipal leaders.
Meanwhile, a seven-year-old child was killed in a different assault in the Zaporizhzhia region in the country's south-east, according to local officials.
Moscow has intensified strikes on energy facilities over the last fortnight, while Ukrainian leadership has requested "real steps" from allies to exert influence on Russia.
"What is required is not symbolic gestures but decisive action - from the United States, Europe and the G7 - in supplying protection systems and enforcing penalties," he wrote in a social media post.
Authorities reported that 450 drones and over thirty projectiles targeted the country's power systems, describing such strikes as "premeditated" and against "everything that sustains normal life" as winter approaches.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were striving to restore power.
A barrage of missiles struck energy infrastructure and civilian homes in Kyiv.
Multiple people hurt in the assaults on the capital have been transported for medical care, according to local officials.
Area administrators said the metropolitan region came under intense attacks during nighttime hours. A seven-year-old child lost their life and multiple civilians were hurt.
The assaults come after nights of aerial attacks in the area, parts of which remain under the control of Moscow's military.
All of Ukraine is under warning for advanced weapon attacks, which are harder to identify.
Authorities told journalists that Russia was deliberately attempting to damage the national power system, with attacks already affecting fuel infrastructure.
Officials stated utility staff and government agencies were preparing for more assaults.
