At least 10 people have been killed in the worst unrest to hit Papua in years, as thousands have taken part in anti-racism rallies.
Human Rights Watch's Australia Director, Elaine Pearson, says the deaths need to be investigated, including a bloody clash in Deiyai regency.
Indonesian police said at least five people and a soldier were killed in Deiyai when security forces were attacked during a riot on August 28.
A former Deiyai resident, John Pakage, said he and hundreds of others have fled the regency.
