Overnight, Moscow's missile and drone strikes have caused blackouts in multiple districts of the capital city, the Ukrainian capital.
Several individuals were injured while local people in the city's east were plunged into darkness and dealt with problems to water supplies, per reports from local authorities.
Simultaneously, a seven-year-old child was fatally injured in a separate aerial attack in the Zaporizhzhia region in the southeastern part, as reported by regional authorities.
Moscow has increased attacks on electrical systems over the past few days, while Ukrainian leadership has called for "substantial measures" from allies to apply pressure on Russia.
"The necessity is not window dressing but decisive action - from the America, European nations and the G7 - in delivering protection systems and applying sanctions," he wrote in a online statement.
Officials stated that numerous aerial vehicles and several dozen rockets targeted Ukraine's energy infrastructure, labeling such attacks as "premeditated" and against "critical infrastructure" as winter approaches.
Energy officials said Russia was "launching a major assault" and technical staff were striving to restore power.
A barrage of missiles hit power facilities and apartment buildings in Kyiv.
Several of the people wounded in the attacks on the city have been transported for medical care, as confirmed by city authorities.
Regional authorities said the urban area came under significant strikes throughout the evening. A minor was killed and several individuals were injured.
The assaults come after periods of aerial attacks 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 more difficult to spot.
Authorities told reporters that Russia was intentionally trying to damage the electrical infrastructure, with assaults already disrupting energy systems.
Authorities confirmed utility staff and authorities were bracing for additional strikes.
