The disaster struck on Friday at the Vale mine near the city of Belo Horizonte in Minas Gerais state, spewing millions of tons of muddy sludge across the facility and down towards farmland alongside the nearby town of Brumadinho. Dozens of helicopters were used in the rescue operation on Saturday because the released mud engulfed buildings, vehicles and roads with a deep, treacherous layer. from World News Headlines, Latest International News, World Breaking News - Times of India http://bit.ly/2Um19m9
