Peru will try to make contact for the first time with an Amazonian tribe that largely lives isolated in the jungle, part of a bid to ease tensions with nearby villages after a bow-and-arrow attack in May.

The “most detailed sightings of uncontacted tribes ever recorded on camera” have been released to illustrate the danger of their lives becoming less isolated.

Peruvian authorities 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.
