A newspaper in Papua has published a letter from the Papuan Freedom Movement apologising to the Indonesian Red Crescent for shooting 3 of the organisation's volunteers in July this year.
The letter in Bintang Papua is signed by two commanders of the movement's military wing, the OPM.
They say shots were fired at an ambulance at a time when the Indonesian army was carrying out operations in Puncak Jaya.
One man died in the shooting and two others were hurt.
The commanders say the person who did the shooting thought the vehicle belonged to the Indonesian military.
