Rare footage reportedly showing uncontacted members of a Brazilian indigenous tribe hunting in the Amazon rainforest has been released by a campaign group in Brazil.

Survival International, a group who champions tribal people's rights, said the Awá tribe's home forest has been under threat by the rapid deforestation and logging.

The video, first shown on Brazilian TV on Sunday night, was used to raise awareness of the Awá tribe's plight.

The video, from Maranhao state in eastern Brazil, was filmed by a neighbouring tribe, the Guajajara, who are trying to protect the islands of rainforest in which the Awá lives. Both tribes have been under threat from the loggers.

A spokesman for Midia India, an indigenous film-making association who filmed the interaction, said: "We need to show that the Awá exist and their lives are at risk.

"We're using these images as a cry for help and we're calling for the government to protect the lives of our relatives who don't want contact with outsiders."

Local environmental groups have expressed concern that logging and deforestation rates are on the increase since Brazilian President Jair Bolsonaro was elected in January 2019.
