An indigenous tribe living in Brazil's Amazon rainforest with little to no exposure to the outside world was captured on film two years ago. The footage was released Wednesday by FUNAI, the indigenous peoples' foundation of Brazil.

The footage depicts a group of nine naked people, said to be members of the Kawahiva tribe, trekking through dense jungle. The men carry bows and a woman walks with a child on her back.

The nomadic tribe relies on hunting and fishing for sustenance, according to FUNAI.

FUNAI reports that the Kawahiva tribe, which was discovered in 1999, may have numbered about 50 people in the past, but that it suspects the population has dwindled in recent years because the tribeswomen and tribesmen have stopped having children because "they are constantly fleeing loggers and other intruders," the group said on its website, going on to suggest that the tribe is facing a genocide.

"Their land has not yet been protected and therefore their survival as a people is at great risk. Their forests are constantly being invaded by loggers many of whom operate out of Colniza, one of Brazil's most violent frontier towns in one of the most deforested regions in the Amazon," FUNAI reported.

According to the website LiveLeak, the video was shot by Jair Candor, reportedly an employee of FUNAI. Candor reportedly said that capturing the indigenous tribe on video was unintended and that the film crew was in the jungle investigating something else. "We were not there to meet them," Candor said, according to LiveLeak. "We had to check out some raids on the edge of the earth."

The footage was reportedly shot in 2011 but was not released until Wednesday of this week.
