During the night, Russian missile and drone strikes have caused electricity outages in large parts of the capital city, Kyiv.
Several individuals were wounded while local people in eastern neighborhoods were left without electricity and dealt with problems to drinking water, according to local authorities.
Simultaneously, a young boy was killed in a separate assault in the Zaporizhzhia region in the southeastern part, as reported by area administrators.
Moscow has increased attacks on energy facilities over recent weeks, while the country's government has requested "real steps" from allies to exert influence on Russia.
"What is required is not window dressing but strong steps - from the America, the EU and the G7 - in delivering defensive weapons and implementing penalties," mentioned in a online statement.
Authorities reported that hundreds of unmanned aircraft and more than 30 missiles targeted energy facilities, characterizing such assaults as "cynical and calculated" and against "critical infrastructure" as the weather cools.
Government representatives said Russia was "conducting extensive attacks" and technical staff were striving to repair systems.
A series of attacks damaged energy infrastructure and civilian homes in Kyiv.
Five out of the nine people injured in the attacks on the capital have been transported for medical care, as confirmed by local officials.
Area administrators said the urban area endured intense attacks during nighttime hours. A young boy lost their life and multiple civilians were wounded.
The assaults succeed nights of bombing campaigns in the region, sections of which are currently controlled by Moscow's military.
All of Ukraine is on alert for sophisticated projectile assaults, which are harder to detect.
Government officials told the media that Moscow was intentionally trying to damage the country's energy grid, with assaults already impacting energy systems.
He said utility staff and government agencies were bracing for additional strikes.
