Overnight, Moscow's missile and drone strikes have resulted in blackouts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were hurt while inhabitants in eastern districts were plunged into darkness and encountered disruption to water supplies, per reports from city officials.
Meanwhile, a minor was killed in a separate Russian drone strike in the Zaporizhzhia region in the southeastern part, according to area administrators.
Moscow has escalated strikes on power infrastructure over the past few days, while the country's government has called for "substantial measures" from partner nations to exert influence on Russia.
"What is required is not window dressing but decisive action - from the US, European nations and the G7 - in delivering defensive weapons and applying penalties," mentioned in a social media post.
He said that hundreds of unmanned aircraft and over thirty projectiles targeted energy facilities, labeling such strikes as "premeditated" and against "essential services" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and technical staff were working to restore power.
A series of attacks damaged electrical systems and residential structures in Kyiv.
Several of the people injured in the assaults on the capital have been transported for medical care, according to city authorities.
Regional authorities said the urban area came under significant strikes throughout the evening. A minor was killed and three other people were wounded.
The strikes follow nights of bombing campaigns in the area, portions of which remain under the control of Moscow's military.
The whole nation is on alert for advanced weapon attacks, which are tougher to detect.
National leaders told journalists that Moscow was deliberately attempting to damage the national power system, with attacks already impacting energy systems.
Authorities confirmed utility staff and authorities were bracing for further attacks.
