During the night, Russian aerial assaults have caused power cuts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were injured while local people in eastern neighborhoods were plunged into darkness and dealt with problems to water systems, according to municipal leaders.
At the same time, a seven-year-old child was fatally injured in a separate aerial attack in the southeastern region in the southern area, based on information from local officials.
Moscow has intensified strikes on electrical systems over the last fortnight, while Ukrainian leadership has called for "real steps" from international partners to apply pressure on Russia.
"The necessity is not symbolic gestures but firm measures - from the United States, the EU and the G7 - in delivering air defence systems and applying sanctions," was stated in a online statement.
Authorities reported that hundreds of unmanned aircraft and several dozen missiles struck Ukraine's energy infrastructure, characterizing such assaults as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
Energy officials said Moscow was "launching a major assault" and maintenance teams were laboring to restore power.
A barrage of missiles damaged power facilities and civilian homes in Kyiv.
Several of the people injured in the strikes on the capital have been transported for medical care, according to city authorities.
Regional authorities said the urban area experienced intense attacks overnight. A young boy died and multiple civilians were hurt.
The assaults come after nights of aerial attacks in the region, portions of which are currently controlled by invading troops.
The entire country is on alert for hypersonic Kinzhal missile strikes, which are tougher to spot.
Government officials told journalists that Russia was purposely seeking to destroy the country's energy grid, with strikes already impacting gas facilities.
Officials stated energy workers and authorities were anticipating further attacks.
