Dam collapse buries Brazilian town under a deadly river of mud
A dam in Brazil collapsed, burying the town of Brumadinho under a deadly river of mud. The dam was meant to contain the byproducts of mining operations. The mine operator, Vale, was involved in a previous dam collapse just a few years ago. Over 115 people were confirmed dead and over 200 missing. Questions emerged about whether the dam was inspected properly or whether corners were cut in construction. Plus, learn how to say events "unfold" in English.
