The West Papua National Coalition for Liberation says Papuan students have been terrorised by Islamic militia and an Indonesian nationalist group in Yogyakarta in recent days.
It says 45 Papuan student leaders have fled their dormitories following threats by Front Pembela Islam and the Indonesian Anti-Communist Front.
The coalition's Jonah Wenda says the threat follows the student demonstrations over Jakarta's decision to ban a US Congressman from visiting Papua last week.
"Islamic militia, they made a statement on July 7th to fight against every Papuan who supports the idea of the separatist movement in West Papua. The TNI and the police did nothing. can say that they're supporting these groups to terrorise the students over there (Yogyakarta)."
Jonah Wenda also claims that in Papua province, Jakarta is sponsoring and arming Islamic militia groups to fight against Papuans.
He such groups are being placed increasingly along the border with Papua New Guinea.
