The armed rebels who kidnapped a New Zealand pilot have threatened to execute him if their demands aren't met.
New footage has emerged of captive Philip Mehrtens surrounded by rebels with guns and bow and arrows, with one fighter warning Mehrtens "will die here" if the Indonesian army tried to rescue him.
Rebel spokesperson Sebby Sambom wrote Mr Mehrtens will be held hostage for negotiations with Indonesia but warned that if terms weren't met then the pilot "will be executed".
