A group of previously isolated indigenous people from the Amazon has come face to face with a settled community of villagers for the first time in the Brazilian state of Acre, according to authorities.
FUNAI, Brazil's Indigenous Affairs Department, has released footage of the meeting.
Experts believe the tribesmen may have left the safety of their tribe because of threats posed by illegal loggers or drug traffickers.
