Overnight, Moscow's missile and drone strikes have resulted in electricity outages in large parts of Ukraine's capital, Kyiv.
A number of civilians were hurt while inhabitants in eastern districts were plunged into darkness and encountered interruptions to drinking water, as stated by municipal leaders.
At the same time, a seven-year-old child was killed in a different aerial attack in the southeastern region in the southern area, as reported by local officials.
Moscow has increased attacks on energy facilities over recent weeks, while the country's government has demanded "substantial measures" from partner nations to increase pressure on Moscow.
"What is required is not symbolic gestures but strong steps - from the US, the EU and the G7 - in supplying air defence systems and enforcing sanctions," he wrote in a online statement.
Officials stated that numerous aerial vehicles and several dozen rockets targeted the country's power systems, describing such assaults as "premeditated" and against "essential services" as the weather cools.
The energy minister said Moscow was "inflicting a massive strike" and technical staff were working to fix the damage.
A barrage of missiles struck energy infrastructure and residential structures in the capital.
Several of the people injured in the strikes on the capital have been taken to hospital, according to city authorities.
Area administrators said the metropolitan region came under intense attacks overnight. A minor died and three other people were hurt.
The assaults come after evenings of air raids in the area, parts of which are occupied by invading troops.
All of Ukraine is under warning for sophisticated projectile assaults, which are tougher to identify.
Government officials told reporters that Moscow was deliberately attempting to damage the national power system, with assaults already disrupting energy systems.
He said technical personnel and officials were bracing for additional strikes.
