Throughout the evening, Moscow's missile and drone strikes have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
Nine people were hurt while inhabitants in the city's east were plunged into darkness and encountered disruption to water supplies, per reports from municipal leaders.
Simultaneously, a minor was killed in a separate Russian drone strike in the Zaporizhzhia area in the country's south-east, based on information from regional authorities.
Moscow has escalated attacks on power infrastructure over the past few days, while Ukrainian leadership has called for "real steps" from international partners to exert influence on Moscow.
"What is required is not symbolic gestures but firm measures - from the US, the EU and the G7 - in providing air defence systems and applying sanctions," he wrote in a social media post.
He said that 450 drones and several dozen projectiles targeted the country's power systems, characterizing such assaults as "cynical and calculated" and against "critical infrastructure" as temperatures become colder.
Government representatives said Moscow was "launching a major assault" and technical staff were working to fix the damage.
A series of attacks hit power facilities and apartment buildings in Kyiv.
Several of the people wounded in the strikes on the capital have been transported for medical care, as confirmed by municipal representatives.
Regional authorities said the metropolitan region experienced heavy assaults during nighttime hours. A young boy lost their life and multiple civilians were wounded.
The strikes succeed periods of bombing campaigns in the region, sections of which are currently controlled by Russian forces.
All of Ukraine is under warning for hypersonic Kinzhal missile strikes, which are tougher to detect.
National leaders told the media that Moscow was deliberately attempting to damage the country's energy grid, with strikes already impacting fuel infrastructure.
Officials stated technical personnel and officials were anticipating additional strikes.
