Amnesty International says the Indonesian government must stop treating peaceful protestors as criminals.
The human rights organisation wants the immediate release of seven people arrested for their involvement in a peaceful political protest and flag raising in Papua.
It says the case highlights the failure of Indonesian authorities to distinguish between armed groups and peaceful political activists.
The seven have been in custody for six months since taking part in a march against injustice and human rights violations.
The organisation is also calling on the Indonesian authorities to withdraw a 2007 government regulation that bans the display of regional flags which are used by separatist movements.
