Overnight, Russian missile and drone strikes have led to blackouts in large parts of Ukraine's capital, Kyiv.
Nine people were wounded while inhabitants in eastern districts were experienced blackouts and encountered problems to drinking water, per reports from city officials.
Simultaneously, a seven-year-old child was killed in a separate assault in the Zaporizhzhia area in the country's south-east, according to regional authorities.
Moscow has increased attacks on energy facilities over the past few days, while Ukrainian leadership has called for "real steps" from allies to apply pressure on Russia.
"The necessity is not superficial actions but firm measures - from the United States, Europe and the Group of Seven - in providing defensive weapons and implementing restrictions," was stated in a online statement.
Authorities reported that hundreds of unmanned aircraft and over thirty missiles attacked the country's power systems, describing such assaults as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
The energy minister said Moscow was "conducting extensive attacks" and maintenance teams were striving to restore power.
A wave of strikes struck electrical systems and civilian homes in the capital.
Multiple people injured in the strikes on the city have been hospitalized, as confirmed by city authorities.
Local officials said the metropolitan region endured heavy assaults during nighttime hours. A minor lost their life and three other people were injured.
The attacks succeed evenings of aerial attacks in the region, sections of which are occupied by Moscow's military.
The whole nation is on alert for advanced weapon attacks, which are more difficult to detect.
Authorities told reporters that Moscow was deliberately attempting to demolish the electrical infrastructure, with assaults already impacting energy systems.
Authorities confirmed energy workers and officials were anticipating further attacks.
