PREVIEW

Heavy rain has caused widespread flooding in the southern Brazilian state of Rio Grande do Sul leaving hundreds of towns under water.

At least 85 people died in the floods and about 150,000 have been displaced from their homes, officials said.

Some towns remain isolated and hopes of finding the more than 130 people who are still missing are dwindling.

Further heavy rains forecast for this week are expected to further exacerbate the situation in the region.

Many residents had to leave their homes, with some of the most vulnerable people evacuated by rescue workers.
