Throughout the evening, Russian missile and drone strikes have led to power cuts in large parts of Ukraine's capital, Kyiv.
Nine people were injured while inhabitants in the city's east were left without electricity and dealt with problems to water systems, according to city officials.
At the same time, a young boy was fatally injured in a different aerial attack in the southeastern region in the southern area, based on information from area administrators.
Moscow has escalated assaults on energy facilities over the last fortnight, while Ukrainian leadership has requested "real steps" from allies to increase pressure on Russia.
"The necessity is not window dressing but strong steps - from the US, Europe and the Group of Seven - in supplying protection systems and implementing penalties," mentioned in a social media post.
Officials stated that hundreds of unmanned aircraft and over thirty rockets struck the country's power systems, characterizing such strikes as "premeditated" and against "essential services" as temperatures become colder.
Energy officials said Moscow was "launching a major assault" and maintenance teams were striving to repair systems.
A wave of strikes struck energy infrastructure and residential structures in Kyiv.
Several of the people injured in the attacks on the city have been transported for medical care, according to local officials.
Area administrators said the metropolitan region came under intense attacks overnight. A seven-year-old child lost their life and multiple civilians were hurt.
The strikes come after evenings of air raids in the area, parts of which are currently controlled by Russian forces.
The entire country is under warning for sophisticated projectile assaults, which are harder to spot.
National leaders told journalists that Russia was deliberately attempting to destroy the electrical infrastructure, with assaults already affecting energy systems.
Officials stated energy workers and government agencies were bracing for more assaults.
