Overnight, Moscow's missile and drone strikes have resulted in electricity outages in large parts of Ukraine's capital, Kyiv.
Nine people were hurt while inhabitants in the city's east were experienced blackouts and dealt with interruptions to drinking water, according to municipal leaders.
Simultaneously, a minor was fatally injured in a different assault in the Zaporizhzhia region in the southeastern part, based on information from area administrators.
Moscow has intensified attacks on electrical systems over the past few days, while Ukrainian leadership has demanded "concrete actions" from partner nations to exert influence on Moscow.
"What is required is not window dressing but strong steps - from the US, Europe and the major economies - in supplying defensive weapons and enforcing sanctions," he wrote in a online statement.
Authorities reported that 450 drones and more than 30 projectiles targeted Ukraine's energy infrastructure, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "inflicting a massive strike" and repair crews were striving to repair systems.
A series of attacks struck electrical systems and civilian homes in the capital.
Five out of the nine people hurt in the assaults on the capital have been taken to hospital, per statements from local officials.
Regional authorities said the urban area came under significant strikes overnight. A young boy died and three other people were injured.
The attacks succeed evenings of air raids in the region, parts of which are currently controlled by Moscow's military.
The whole nation is under warning for hypersonic Kinzhal missile strikes, which are tougher to identify.
National leaders told the media that Moscow was deliberately attempting to damage the electrical infrastructure, with attacks already affecting gas facilities.
He said utility staff and government agencies were anticipating more assaults.
