At least nine people were killed and nearly 300 are missing after the collapse of a disused dam at an iron-ore mine complex in the southeastern part of Brazil.

The collapse took place when the dam, owned by Brazilian mining giant Vale, broke apart, sending a massive torrent of mud over the complex where over 300 mine employees were working. Officials said they are evaluating the full scope of the disaster.

The death toll is expected to rise as rescue teams use earth-moving machinery at the site near the town of Brumadinho, in Minas Gerais state.
