Hopes of finding survivors of mudslides and floods on Thursday in Brazil are fading, the governor of Minas Gerais state has said.

A huge wall of red sludge descended on the south-eastern village of Bento Rodrigues when two dams holding waste water from an iron ore mine collapsed.

Hundreds of rescue workers continue to search for 28 people who are missing feared dead.

The authorities have confirmed the death of one person.

Two other bodies have been retrieved, but officials are not sure whether their deaths were connected to the breach of the dams on Thursday afternoon.

They will carry out DNA tests to check if they are related to the 13 mine workers and 15 residents, including five children, who are missing.
