Alert as torrential rains kill dozens in Bolivia floods

Hundreds of towns and villages in Bolivia have been put under alert as torrential rains continue to wreak havoc in the South American country.

Officials say 33 people have died since November due to the rains, which have triggered landslides and caused rivers to burst their banks.

The death toll is eight times higher than in the same period last year.

Officials are carefully monitoring a number of dams which they fear could overflow.
