LIMA, Peru (AP) — Peruvian authorities say they are struggling to keep outsiders away from a clan of previously isolated Amazon Indians who began appearing on the banks of a jungle river popular with environmental tourists last year.
The behavior of the small group of Mashco-Piro Indians has puzzled scientists. They say it may be related to encroachment by loggers and by low-flying aircraft from nearby natural gas and oil exploration in the southeastern region of the country.
Clan members have been blamed for two bow-and-arrow attacks on people near the riverbank in Madre de Dios state where officials say the Indians were first seen last May.
