Lost tribe of 200 discovered in Amazon rainforest
A lost tribe of 200 people has been discovered in Brazil's Amazon rainforest, living in a valley close to Peru's border.
Picture of the tribe - who has never had contact with the outside world - were taken by air surveillance.
Fabricio Amorim, of the National Indian Foundation (FUNAI), said that the Indians lived in four large villages growing corn, bananas, peanuts and other crops.
He warned that the tribe faced a number of threats including illegal fishing, hunting, logging and drug trafficking.
He added that they were also at risk from oil exploration on the Peruvian side of the border.
FUNAI's policy is not to contact the Indians, but to monitor their land so that they can live there undisturbed.
The Javari Valley where they live is home to the highest concentration of uncontacted tribes in the world with around 2,000 people.
