Overnight, Russian missile and drone strikes have resulted in power cuts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were wounded while inhabitants in eastern neighborhoods were plunged into darkness and encountered problems to drinking water, as stated by municipal leaders.
Meanwhile, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia area in the southeastern part, according to regional authorities.
Moscow has intensified strikes on electrical systems over the past few days, while the country's government has called for "concrete actions" from international partners to apply pressure on Moscow.
"What is required is not window dressing but strong steps - from the United States, the EU and the Group of Seven - in delivering protection systems and enforcing penalties," mentioned in a social media post.
Authorities reported that hundreds of unmanned aircraft and more than 30 rockets attacked energy facilities, labeling such strikes as "premeditated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Russia was "conducting extensive attacks" and technical staff were striving to fix the damage.
A series of attacks struck energy infrastructure and civilian homes in the capital.
Several of the people hurt in the attacks on the city have been hospitalized, as confirmed by city authorities.
Local officials said the urban area came under intense attacks throughout the evening. A young boy died and several individuals were injured.
The attacks follow evenings of air raids in the territory, portions of which remain under the control of invading troops.
All of Ukraine is in a state of readiness for sophisticated projectile assaults, which are tougher to detect.
National leaders told reporters that Russia was intentionally trying to destroy the national power system, with assaults already disrupting energy systems.
Authorities confirmed technical personnel and officials were bracing for more assaults.
