During the night, Moscow's missile and drone strikes have resulted in blackouts in large parts of Ukraine's capital, Kyiv.
Several individuals were injured while residents in the city's east were experienced blackouts and faced problems to drinking water, as stated by local authorities.
Meanwhile, a minor was fatally injured in a separate assault in the southeastern region in the southeastern part, based on information from area administrators.
Moscow has intensified attacks on power infrastructure over the last fortnight, while Ukrainian leadership has called for "real steps" from allies to increase pressure on Russia.
"The necessity is not superficial actions but strong steps - from the US, the EU and the major economies - in providing defensive weapons and applying restrictions," was stated in a online statement.
Authorities reported that hundreds of unmanned aircraft and over thirty rockets struck Ukraine's energy infrastructure, characterizing such attacks as "cynical and calculated" and against "essential services" as winter approaches.
Energy officials said Russia was "conducting extensive attacks" and repair crews were working to restore power.
A barrage of missiles hit energy infrastructure and civilian homes in the capital.
Five out of the nine people injured in the strikes on the capital have been taken to hospital, according to local officials.
Area administrators said the city endured heavy assaults during nighttime hours. A minor died and several individuals were injured.
The assaults come after evenings of air raids in the region, parts of which remain under the control of Russian forces.
The entire country is in a state of readiness for advanced weapon attacks, which are more difficult to detect.
Government officials told journalists that Moscow was purposely seeking to destroy the electrical infrastructure, with strikes already disrupting fuel infrastructure.
Authorities confirmed energy workers and government agencies were bracing for additional strikes.
