Police in southern Brazil killed one Terena indigenous protester and wounded several others while evicting them from their land on Thursday of last week.
Police claim that they had been attacked by bows and arrows. For two weeks several hundred Terena people had occupied a farm built on their ancestral land and owned by a local politician.
They successfully re-occupied the farm on Friday.
The land is in Mato Grosso do Sul, one of the main soya producing regions of Brazil. Big farmers there often use violence to force indigenous people from their land.
Similar police violence could be used against indigenous people occupying a construction site of the Belo Monte hydroelectric dam following an eviction order.
These attacks come as a lost report into the treatment of indigenous people was found in an archive.
The report investigated the widespread state-sanctioned murder and dispossession of indigenous people in the 1960s.
The report disappeared 40 years ago—soon after its conclusions were made public—and was thought to be destroyed.
