ADVERTISEMENTA reservoir damn collapsed in the Ural Mountains region of Chelyabinsk on Friday night, forcing residents of nearby villages to evacuate their homes.
The dam at the Kialimskoye reservoir was unable to hold back rising waters due to heavy rainfall and broke, impacting four villages in the nearby region.
