Overnight, Moscow's missile and drone strikes have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
Several individuals were hurt while inhabitants in eastern districts were left without electricity and faced problems to water systems, according to city officials.
Meanwhile, a seven-year-old child was fatally injured in a separate assault in the Zaporizhzhia area in the southern area, as reported by regional authorities.
Moscow has intensified attacks on electrical systems over the past few days, while Ukrainian leadership has requested "substantial measures" from allies to apply pressure on Moscow.
"The necessity is not window dressing but firm measures - from the United States, the EU and the Group of Seven - in delivering air defence systems and applying sanctions," he wrote in a online statement.
He said that hundreds of unmanned aircraft and more than 30 missiles attacked Ukraine's energy infrastructure, describing such assaults as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Moscow was "launching a major assault" and repair crews were striving to repair systems.
A barrage of missiles struck electrical systems and apartment buildings in the capital.
Five out of the nine people injured in the attacks on the capital have been transported for medical care, according to municipal representatives.
Area administrators said the city endured significant strikes overnight. A seven-year-old child was killed and several individuals were injured.
The strikes follow nights of bombing campaigns in the area, parts of which are currently controlled by invading troops.
All of Ukraine is under warning for sophisticated projectile assaults, which are more difficult to detect.
National leaders told journalists that Moscow was deliberately attempting to demolish the national power system, with assaults already disrupting energy systems.
Officials stated technical personnel and authorities were preparing for further attacks.
