Throughout the evening, Moscow's aerial assaults have led to power cuts in multiple districts of Ukraine's capital, Kyiv.
Several individuals were hurt while local people in the city's east were experienced blackouts and dealt with problems to drinking water, per reports from local authorities.
At the same time, a seven-year-old child was killed in a separate aerial attack in the southeastern region in the country's south-east, as reported by regional authorities.
Moscow has escalated attacks on energy facilities over the past few days, while Ukrainian leadership has called for "substantial measures" from international partners to exert influence on Russia.
"The necessity is not window dressing but strong steps - from the United States, European nations and the major economies - in delivering air defence systems and implementing penalties," he wrote in a social media post.
Officials stated that 450 drones and several dozen rockets attacked Ukraine's energy infrastructure, describing such strikes as "cynical and calculated" and against "essential services" as the weather cools.
The energy minister said Moscow was "launching a major assault" and technical staff were laboring to fix the damage.
A barrage of missiles damaged electrical systems and residential structures in Kyiv.
Five out of the nine people wounded in the attacks on the capital have been taken to hospital, according to municipal representatives.
Regional authorities said the urban area endured intense attacks overnight. A seven-year-old child died and three other people were wounded.
The attacks follow nights of bombing campaigns in the region, sections of which are occupied by Moscow's military.
The entire country is on alert for advanced weapon attacks, which are harder to detect.
National leaders told reporters that Russia was purposely seeking to destroy the electrical infrastructure, with assaults already affecting energy systems.
Authorities confirmed technical personnel and authorities were anticipating additional strikes.
