'Uncontacted' Indians photographed during overflight in May 2008 in Brazil

Brazilian officials say they have located and photographed one of the country's last uncontacted tribes in the remote western Amazon jungle near the border with Peru.

Of the more than 100 uncontacted tribes in the world, more than half live in the Brazil-Peru area.

Jose Carlos Meirelles from the Brazilian National Indian Foundation said the tribe is threatened by illegal logging which is encroaching on their territory and could force them off their land.

He says they have been monitoring four distinct groups in the area for the past 20 years

Advocates for indian tribes are calling on countries to enforce international law in an effort to protect the people's habitat.
