More than 500 people have now died in Brazil's floods

At least 500 people are now known to have died in Brazil as a result of flash floods and landslides in the south east of the country.

But the death toll is expected to rise even higher as rescuers reach remote areas that have been cut off.

It's the worst natural disaster Brazil has seen for decades.

Thousands of people have been left homeless.
