Nearly 50 people have died in Brazil and thousands have been evacuated from their homes after intense rainfall spawned widespread flooding and triggered landslides, according to officials.

Most of the casualties were reported in the state of Minas Gerais, where many of the victims were buried in landslides or washed away in floods after intense rain on Friday and Saturday.

On Sunday, authorities in the area said at least 37 people had died, while more than 17,000 were displaced or evacuated from their homes.

The floods and landslides come on the first anniversary of the dam collapse near the town of Brumadinho, southwest of Belo Horizonte, that killed 270 people.

Mining giant Vale and German auditor Tüv Süd now face environmental charges relating to the collapse, with 16 individuals who worked for the companies facing charges of murder. Vale has been accused of failing to report warning signs before the dam engulfed a canteen, offices and farms.
