Police are pursuing an armed group who shot and killed two police officers and a security guard stationed at a huge US-owned copper and gold mine in the Indonesian province of Papua.
The three men were found dead with bullet and machete wounds at the remote Freeport-McMoRan mine in Grasberg on Thursday night.
A Papua police spokesman, Patrick Renwarin, told AFP that police found deep gashes on the bodies as well as bullet wounds on one of them.
Mr Renwarin says he is still waiting for a full report on the incident.
The mine is the world's second-biggest copper and gold mine.
It has been plagued with tragedy including the death of 28 workers after a tunnel collapse in May 2013.
