Indians who are considered uncontacted by anthropologists, react to a plane flying over their community in the Amazon basin near the Xinane river in Brazil's Acre State, Brazil, March 25, 2014. Leaders of the Ashaninka tribe, which shares territory with this tribe and other uncontacted ones, have asked the government and NGOs for help in controlling what they consider the encroachment of these tribes on their own area, stating that the movement of other tribes is caused by pressure from illegal logging across the border in Peru.
