Overnight, Russian missile and drone strikes have led to blackouts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were hurt while residents in the city's east were experienced blackouts and encountered interruptions to drinking water, as stated by municipal leaders.
Simultaneously, a young boy was killed in a separate aerial attack in the Zaporizhzhia region in the southern area, according to regional authorities.
Moscow has escalated attacks on energy facilities over recent weeks, while Ukrainian leadership has demanded "real steps" from international partners to apply pressure on Russia.
"What is required is not superficial actions but strong steps - from the US, the EU and the major economies - in delivering air defence systems and applying restrictions," he wrote in a online statement.
Officials stated that 450 drones and over thirty missiles struck energy facilities, characterizing such strikes as "premeditated" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "inflicting a massive strike" and technical staff were working to repair systems.
A series of attacks struck electrical systems and civilian homes in Kyiv.
Multiple people wounded in the strikes on the capital have been taken to hospital, according to local officials.
Area administrators said the city endured significant strikes overnight. A minor died and several individuals were injured.
The attacks come after periods of air raids in the territory, portions of which are currently controlled by invading troops.
The entire country is in a state of readiness for advanced weapon attacks, which are harder to spot.
National leaders told reporters that Moscow was deliberately attempting to demolish the country's energy grid, with strikes already impacting gas facilities.
Authorities confirmed technical personnel and government agencies were preparing for further attacks.
