Brazil: fears for isolated Amazon tribes as fires erupt on protected reserves

• Fires broke out in 131 indigenous reserves from 15-20 August
• Campaigners say indigenous territories easy targets for loggers

Fires have been reported in protected indigenous reserves of the Brazilian Amazon, raising fears that loggers and land grabbers have targeted these remote areas during the dramatic surge in blazes across the world's biggest rainforest.

Blazes have been seen on the Arariboia indigenous reserve in Maranhio state - a heavily deforested reserve on the Amazon's eastern fringes, which is home to about 80 people from an isolated group of Awi indigenous people, described by the NGO Survival International as the world's most endangered tribe.
