Reports emerging from Indonesia's Papua province say security forces have opened fire on delegates attending the Third Papuan People's Congress in Jayapura.
West Papua Media Alerts reports that military troops have fired on the Papuans converging on Taboria Oval, the site of the Congress.
Indonesian news agencies report at least one person was killed and others injured.
The Asian Human Rights Commission has voiced concern at what it calls the disproportionate deployment of over two-thousand security forces to the Congress.
The Commission's Norman Voss says the event is a peaceful and legal assembly where the Papuans are within their rights to gather.
"And the question of why the national army is repeatedly involved in these events is very unclear because these are not issues of major civil unrest. These are civil actions and the extent to which the military is involved is unreasonable and not justifiable."
