Group releases photos of uncontacted tribe to raise awareness.

(CNN) -- In an effort to ramp up pressure for Peru to crack down on illegal loggers in its region of the Amazon, an indigenous rights organization has released what it says are photos of an uncontacted tribe in Brazil that is threatened by the logging across the border.
Survival International says the previously unpublished aerial photos, which it released Monday, show members of an uncontacted Brazilian tribe that is likely to get drawn into conflicts with Peruvian tribes who are fleeing their homes because of the logging.
