Rare footage of purportedly uncontacted members of a Brazilian indigenous tribe hunting in the Amazon rainforest was released Monday by activists who warn the group could be wiped out by logging.

The 58-second clip filmed in the northern state of Maranhao shows members of the Awa tribe, which Survival International says has been frequently attacked by loggers who have been emboldened by pro-business President Jair Bolsonaro.

"Only a global outcry stands between them and genocide," said Stephen Corry, director of Survival International, which published the video that had been shot by a member of neighboring indigenous tribe Guajajara. The footage was shot in August, the NGO said.

"Loggers have already killed many of their relatives and forced others out of the forest.

"President Bolsonaro and his friends in the logging industry would like nothing more than for those who still survive to be eliminated."
