During the night, Moscow's missile and drone strikes have resulted in power cuts in extensive areas of Ukraine's capital, Kyiv.
Several individuals were hurt while inhabitants in eastern districts were experienced blackouts and encountered disruption to water supplies, per reports from municipal leaders.
Meanwhile, a young boy was killed in a different Russian drone strike in the Zaporizhzhia area in the southern area, based on information from regional authorities.
Russian forces has increased strikes on electrical systems over the last fortnight, while the country's government has called for "concrete actions" from international partners to increase pressure on Moscow.
"What's needed is not superficial actions but strong steps - from the US, European nations and the Group of Seven - in delivering defensive weapons and applying penalties," mentioned in a social media post.
Authorities reported that numerous aerial vehicles and several dozen missiles struck Ukraine's energy infrastructure, characterizing such attacks as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Government representatives said Moscow was "launching a major assault" and technical staff were striving to restore power.
A barrage of missiles damaged energy infrastructure and civilian homes in Kyiv.
Five out of the nine people injured in the strikes on the city have been taken to hospital, as confirmed by municipal representatives.
Local officials said the city endured significant strikes overnight. A minor died and three other people were hurt.
The assaults follow evenings of bombing campaigns in the territory, sections of which are occupied by Russian forces.
All of Ukraine is in a state of readiness for hypersonic Kinzhal missile strikes, which are harder to spot.
Government officials told journalists that Russia was deliberately attempting to damage the electrical infrastructure, with attacks already impacting energy systems.
Officials stated energy workers and authorities were bracing for more assaults.
