At least 34 people have been killed and about 300 others remain missing after a dam collapsed at an iron ore mine in south-eastern Brazil, officials say.

Rescue teams have been scouring the site near the town of Brumadinho, following Friday’s collapse.

It is not clear what caused the failure of the dam, owned by Vale, Brazil’s largest mining company.

Vale has had 6bn reais ($1.6bn; £1.2bn) frozen from its accounts to help fund recovery works and handle damages.

The rupture of the dam caused a sea of muddy sludge to bury the site’s cafeteria, where workers were eating lunch on Friday.
