RIO DE JANEIRO (Reuters) - Dramatic photographs of previously unfound Amazon Indians have highlighted the precariousness of the few remaining "lost" tribes and the dangers they face from contact with outsiders.

The bow-and-arrow wielding Indians in the pictures released on Thursday are likely the remnants of a larger tribe who were forced deeper into the forest by encroaching settlement, experts said.
