The strike comes amid the ongoing attacks from Russia targeting critical energy infrastructure across the country.   The infrastructure facility in Kyiv was hit in the afternoon, according to the mayor of the city.      

"One of the infrastructure facilities of the capital was hit," Vitalii Klitschko said on Telegram, warning residents to stay in air raid shelters, reported CNN.      

Ukrainian air defense systems were "working in the region," according to Oleksii Kuleba, the governor of the wider Kyiv region.      

Earlier on Wednesday, various missiles hit Ukrainian cities after which air raid warning was issued.      

"There are a lot of missiles. From the south and from the east," Vitalii Kim, head of the Mykolaiv region military administration, said on Telegram. 

"The air defense is working."      

The conflict has escalated in southern and eastern regions of Ukraine in recent days, with local officials citing "massive shelling" in towns and villages on the eastern front line of the Donetsk region, according to CNN.      

After the missile hit Kyiv, water supply has been suspended after shelling in the region, Mayor Vitali Klitschko said in a post on Telegram.      

Klitschko asked residents to "stock up on water" while experts tried to "return water to the homes of Kyiv residents."      

Engineers were also working to restore power supply, Klitschko said. 

Parts of the city are without power after Moscow reportedly targeted infrastructure facilities in the region, the country's biggest energy supplier, Yasno, said in a statement, as per CNN report. -- ANI
