What is "jururei"

Jururei is a tiny uncontacted Indian tribe numbering 8-10 people living in the Parque Nacional Pakaas Novas inside the Terra Indigena Uru-Eu-Uaw-Uaw in Rondônia State, Brazil. In 2005 their land was invaded by loggers who tried to wipe them out. It is not known how many of the tribespeople were killed in the conflict that followed. When FUNAI officials visited their only village, it was abandoned and huts were destroyed.
