Amnesty International is calling for Chile to investigate the use of police force against the Mapuche community. There are some one million Mapuche in Chile. They live in small communities across the country and are often poor and discriminated against. Security forces evicted the indigenous group from land they say is their ancestral property. The community has now stepped up its efforts to fight for what they say historically belongs to them. Al Jazeera's Teresa Bo reports from the Araucania Region.
