Overnight, Moscow's missile and drone strikes have resulted in blackouts in large parts of the capital city, Kyiv.
A number of civilians were injured while local people in the city's east were left without electricity and dealt with interruptions to water supplies, as stated by city officials.
At the same time, a minor was lost their life in a different assault in the southeastern region in the country's south-east, based on information from regional authorities.
Moscow has intensified strikes on electrical systems over recent weeks, while the country's government has demanded "substantial measures" from international partners to apply pressure on Russia.
"What is required is not window dressing but firm measures - from the US, the EU and the major economies - in providing air defence systems and enforcing restrictions," was stated in a public message.
Officials stated that 450 drones and several dozen rockets targeted energy facilities, characterizing such attacks as "strategic and deliberate" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "conducting extensive attacks" and technical staff were laboring to restore power.
A barrage of missiles damaged power facilities and apartment buildings in the capital.
Several of the people wounded in the attacks on the city have been transported for medical care, as confirmed by municipal representatives.
Local officials said the urban area experienced significant strikes during nighttime hours. A minor died and multiple civilians were injured.
The assaults follow nights of bombing campaigns in the region, parts of which are currently controlled by Moscow's military.
The whole nation is in a state of readiness for sophisticated projectile assaults, which are tougher to spot.
Authorities told journalists that Moscow was purposely seeking to damage the country's energy grid, with assaults already affecting gas facilities.
He said technical personnel and authorities were bracing for more assaults.
