New alert as hundreds feared dead in Brazil dam disaster An alarm warning of an imminent mining dam rupture went up early Sunday in Brumadinho, the same Brazilian community where a dam collapsed killing 37 with hundreds more feared dead, firefighters and the mining company said. The alert, warning of dangerously high water levels at a dam that is part of the Corrego do Feijao mining complex in southeastern Brazil, went off at 5:30 am (0730 GMT), a statement by the mining company Vale said. A dam at the same mining site burst Friday, spewing millions of tons of treacherous sludge and engulfing buildings, vehicles and roads.
