Brazil dam collapse: New video shows moment of dam burst

The wave of mud is now moving towards a major river and may contaminate water supplies.

Dramatic new video has been released showing the moment a dam burst in southeastern Brazil.

A week later, at least 115 people have been killed and hundreds are still missing and the wave of mud is making its way toward a major river.

Amid grief and recriminations, many worry about the future, with area dependent on a mine now swallowed by the mud.
