During the night, Russian missile and drone strikes have caused electricity outages in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were hurt while local people in eastern districts were experienced blackouts and faced interruptions to drinking water, per reports from city officials.
Meanwhile, a young boy was killed in a distinct Russian drone strike in the Zaporizhzhia region in the southern area, based on information from area administrators.
Moscow has increased strikes on energy facilities over the past few days, while officials has requested "concrete actions" from allies to increase pressure on Moscow.
"The necessity is not symbolic gestures but strong steps - from the US, the EU and the major economies - in delivering air defence systems and implementing restrictions," was stated in a social media post.
Authorities reported that hundreds of unmanned aircraft and several dozen rockets targeted the country's power systems, describing such assaults as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
The energy minister said Russia was "launching a major assault" and maintenance teams were striving to repair systems.
A series of attacks hit energy infrastructure and residential structures in the capital.
Multiple people injured in the assaults on the city have been hospitalized, per statements from municipal representatives.
Area administrators said the city experienced intense attacks overnight. A young boy was killed and multiple civilians were hurt.
The attacks succeed evenings of bombing campaigns in the area, sections of which are occupied by invading troops.
The whole nation is in a state of readiness for advanced weapon attacks, which are harder to identify.
Government officials told reporters that Russia was deliberately attempting to damage the national power system, with strikes already impacting fuel infrastructure.
Authorities confirmed technical personnel and officials were bracing for more assaults.
