The president of the regional FENAMAD indigenous federation says more than 100 Mashco-Piro appeared across a river from the remote community of Monte Salvado in Madre de Dios state.
Klaus Quicque says they asked local Yine people for bananas, rope and machetes.
Newly available video that Quique says was shot by forest rangers over three days in June shows Mashco-Piro of all ages and sexes, including men with lances, bows and arrows.
Quicque said yesterday there were tense moments but rangers persuaded the Mashco-Piro not to cross the river, directing them to a banana patch.
