During the night, Russian aerial assaults have led to power cuts in extensive areas of Ukraine's capital, Kyiv.
Several individuals were injured while local people in the city's east were left without electricity and faced interruptions to water supplies, per reports from local authorities.
Meanwhile, a young boy was fatally injured in a separate Russian drone strike in the Zaporizhzhia area in the southern area, based on information from local officials.
Moscow has intensified strikes on electrical systems over recent weeks, while Ukrainian leadership has called for "concrete actions" from allies to increase pressure on Russia.
"What's needed is not symbolic gestures but firm measures - from the America, Europe and the Group of Seven - in supplying air defence systems and enforcing penalties," mentioned in a social media post.
He said that numerous aerial vehicles and more than 30 missiles struck the country's power systems, describing such strikes as "strategic and deliberate" and against "everything that sustains normal life" as winter approaches.
Energy officials said Russia was "conducting extensive attacks" and technical staff were working to repair systems.
A wave of strikes struck energy infrastructure and civilian homes in the capital.
Multiple people injured in the strikes on the capital have been taken to hospital, as confirmed by municipal representatives.
Local officials said the city came under intense attacks overnight. A young boy died and three other people were injured.
The strikes come after periods of aerial attacks in the region, parts of which are occupied by invading troops.

Authorities told the media that Russia was intentionally trying to demolish the electrical infrastructure, with assaults already disrupting gas facilities.
He said technical personnel and officials were preparing for further attacks.
