A top Brazilian expert on isolated Amazon tribes has been killed by an arrow that struck him in the chest as he approached an indigenous site.
Rieli Franciscato, 56, died on Wednesday in a remote region of Rondônia state in north-western Brazil.
He was in the area to monitor a tribe as part of his work for the government’s indigenous agency, Funai.
Witnesses said Mr Franciscato and his party came under fire as they approached an indigenous group.
Mr Franciscato, who was accompanied by police, attempted to take shelter behind a vehicle, but was struck in the chest by an arrow, witnesses said.
