During the night, Moscow's aerial assaults have caused power cuts in extensive areas of Ukraine's capital, Kyiv.
Nine people were wounded while local people in eastern districts were plunged into darkness and dealt with interruptions to drinking water, per reports from city officials.
Meanwhile, a minor was fatally injured in a separate aerial attack in the Zaporizhzhia area in the country's south-east, based on information from regional authorities.
Russian forces has escalated attacks on energy facilities over the past few days, while Ukrainian leadership has requested "concrete actions" from international partners to increase pressure on Russia.

He said that 450 drones and over thirty rockets attacked the country's power systems, describing such strikes as "strategic and deliberate" and against "everything that sustains normal life" as temperatures become colder.
Energy officials said Moscow was "inflicting a massive strike" and repair crews were striving to fix the damage.
A barrage of missiles struck power facilities and residential structures in the capital.
Five out of the nine people wounded in the attacks on the city have been transported for medical care, according to municipal representatives.
