The Indonesia military is reportedly waging a campaign of fear throughout the Puncak Jaya region of West Papua in Indonesia over a looming deadline.

An Australia-based NGO says the military is conducting a sweep operation, and has given the civilian population until June 28th to hand over weapons.

The Australian West Papua Association claims military excursions over recent days have triggered clashes with OPM Free West Papua Movement groups and left one Papuan dead.

The Association's Joe Collins says the military is going from village to village, imposing curfews, asking for ID and threatening communities, often beating them.

He says the military appears to be manouevring for a major operation.
