Peru’s reclusive Mashco Piro ethnic group recently used bows and arrows to attack loggers suspected of encroaching on their territory in the Amazon, according to a regional Indigenous organization.

FENAMAD, representing 39 Indigenous communities in the Cusco and Madre de Dios regions, said Monday that it believes illegal logging was taking place on Mashco Piro territory and that one logger was injured in the July 27 attack.
