Overnight, Moscow's missile and drone strikes have caused electricity outages in large parts of Ukraine's capital, Kyiv.
A number of civilians were injured while inhabitants in the city's east were experienced blackouts and faced interruptions to water supplies, according to municipal leaders.
Simultaneously, a young boy was killed in a different Russian drone strike in the Zaporizhzhia area in the southeastern part, according to area administrators.
Moscow has intensified strikes on electrical systems over the last fortnight, while Ukrainian leadership has called for "substantial measures" from international partners to apply pressure on Russia.
"What is required is not superficial actions but strong steps - from the America, European nations and the G7 - in supplying defensive weapons and enforcing restrictions," he wrote in a social media post.
Officials stated that 450 drones and more than 30 missiles struck Ukraine's energy infrastructure, labeling such strikes as "strategic and deliberate" and against "everything that sustains normal life" as the weather cools.
Energy officials said Russia was "launching a major assault" and maintenance teams were working to repair systems.
A series of attacks hit energy infrastructure and civilian homes in Kyiv.
Five out of the nine people wounded in the strikes on the city have been hospitalized, as confirmed by local officials.
Regional authorities said the city experienced intense attacks during nighttime hours. A minor died and three other people were wounded.
The strikes come after periods of bombing campaigns in the region, parts of which are occupied by Russian forces.
The whole nation is in a state of readiness for advanced weapon attacks, which are harder to spot.
Government officials told reporters that Moscow was intentionally trying to destroy the national power system, with attacks already impacting fuel infrastructure.
Officials stated utility staff and government agencies were preparing for additional strikes.
