Brazil dam burst: BHP boss to inspect disaster zone with dozens still missing

Shares in the mining multinational continued to fall amid calls for more regulation in the wake of the collapse of two dams at its co-owned iron ore mine

The boss of BHP Billiton will arrive in Brazil on Monday to see at first-hand the devastation wrought by the collapse of a dam at an iron ore mine co-owned by the company that has left at least two dead and dozens missing.

Three days after the rupturing of two dams unleashed a massive flood of mud on nearby villages, authorities were still struggling to determine the cause of the disaster or even recover the bodies of as many as 28 people lost in the torrent.
