Around 200 residents were evacuated from an area near a tailings dam in Brazil operated by Vale late on Saturday, amid fears that it was structurally weak and could burst like a similar barrier failure last month that killed 300 people.
Vale said in a statement that it had evacuated people living near the inactive B3/B4 dam of the Mar Azul mine about 25 km south of Belo Horizonte, the capital of Minas Gerais state, after revising security data on the structure.
