During the night, Moscow's aerial assaults have caused 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 local authorities.
Simultaneously, a seven-year-old child was killed in a separate assault in the Zaporizhzhia area in the southern area, based on information from area administrators.
Moscow has escalated assaults on power infrastructure over the last fortnight, while the country's government has called for "substantial measures" from allies to apply pressure on Moscow.
"The necessity is not symbolic gestures but strong steps - from the America, the EU and the major economies - in providing protection systems and implementing penalties," he wrote in a public message.
Authorities reported that hundreds of unmanned aircraft and several dozen missiles targeted energy facilities, describing such strikes as "premeditated" and against "critical infrastructure" as the weather cools.
Energy officials said Moscow was "conducting extensive attacks" and maintenance teams were striving to restore power.
A barrage of missiles damaged energy infrastructure and residential structures in the capital.
Five out of the nine people injured in the assaults on the capital have been hospitalized, per statements from city authorities.
Regional authorities said the city experienced significant strikes overnight. A young boy lost their life and several individuals were hurt.
The assaults come after evenings of air raids in the region, parts of which remain under the control of Moscow's military.
All of Ukraine is on alert for sophisticated projectile assaults, which are harder to identify.
Authorities told journalists that Moscow was deliberately attempting to demolish the electrical infrastructure, with strikes already affecting energy systems.
Authorities confirmed energy workers and officials were bracing for further attacks.
