The kidnapping of a New Zealand pilot by separatists in Indonesia's West Papua region has thrust a decades-old insurgency back into the spotlight.
Philip Mehrtens, 37, was taken hostage by West Papua National Liberation Army fighters (TPNPB) in February.
The rebels have been holding him captive as a political prisoner in the remote Nduga region and this week attacked a number of Indonesian troops sent to rescue him, killing at least one.
Mr Mehrtens' kidnapping is the latest flashpoint in a long-running, often brutally violent conflict between the Indonesian government and West Papua's indigenous people.
