Uncontacted Amazon Tribes Shake Spears at Photo Plane Overhead

A series of pictures of a remote, uncontacted tribe in the Amazon basin has been released.

The pictures were taken near the Xinane river in Brazil's Acre State, close to its border with Peru.

The tribe was first identified as "uncontacted" in 2011 when satellite pictures revealed this community was living near the border with Peru.

The Brazilian government confirmed that these indigenous people number about 200. The first photos of their dwellings were taken during a flight in April 2011.

In the latest pictures, taken on 25 March, the uncontacted people are seen reacting to a plane flying overhead.

As many as five tribal men can be seen raising their weapons in a threatening manner at the plane.

Brazil follows a policy of not contacting these people but monitors their land so that they can live without any risk.

However, the community and their dwellings are threatened by illegal logging, mining, cattle ranching, fishing and hunting across the Peru-Brazil border area.

Leaders of the Ashaninka tribe, which shares territory with this tribe and other uncontacted ones in the Amazon, have asked the government and NGOs for help in controlling the encroachment of these tribes in their own area, according to Reuters.

According to Survival International, an organisation working for tribal people's rights worldwide, this Amazonian tribe grows crops, peanuts, bananas, corns and more.

The pictures also show banana plants near the tribe's straw-roofed huts.
