JAKARTA - A GRISLY video of Indonesian security forces torturing suspected separatists in Papua province - burning the genitals of one and running a knife across the neck of another - has sparked public outcry after circulating online.

Although questions are being raised over whether the video is authentic or a stunt by the separatists, it made headlines in local newspapers yesterday and drew angry reactions.

The body of one of the victims, Werius Selenggen, was found near a river late last year soon after security forces were caught on tape interrogating the 38-year-old in the mountainous village of Puncak Jaya, said Mr Matius Murib, of the National Commission on Human Rights.

In the 10-minute clip, Selenggen had denied any knowledge of a hidden stash of weapons. One man threatened to shoot him in the mouth with a rifle and another poked at his genitals with a burning stick, causing him to scream in agony.

A third put a cigarette out in his face.

The identity and whereabouts of the second victim - threatened repeatedly with a heavy knife - are not known.
