An uncontacted Amazon tribe that made headlines earlier this year after being filmed from the air is feared missing after presumed drug traffickers overran the Brazilian guards posted to protect the tribe's lands.
According to tribal advocacy group Survival International, Brazilian officials can find no trace of the Indians in the area after heavily armed men ransacked the guard post in western Brazil about 32 miles (20 kilometers) from the Peruvian border. Like other uncontacted tribes, the Indians live a traditional life in the forest and does not have contact with the outside world.
Workers from FUNAI, the government bureau of Indian affairs, found a broken arrow in one of the men's backpacks, raising fears for the tribe's safety.
