The search continues for four Indonesian workers missing in Papua's remote Highlands after at least 16 of their colleagues were killed by militants.
Police and military are chasing fighters from the West Papua Liberation Army, which has claimed resposibility for this month's attack.
The Liberation Army said the construction workers were military in disguise.
The Jakarta Post reported an Indonesia's security minister, Wiranto, saying it was hoped the four would be found alive.
According to survivors' accounts, the four suffered stab wounds before they escaped.
