The Thai government blames Islamic separatists for rising tensions in the South. But police brutality is isolating the Muslim population.Secret footage shows the police attacking unarmed protestors. Some were beaten so badly, their necks were broken. "Thai Muslims are treated differently to Thai Buddhists," complains one man. Every night, insurgents attack security posts and steal weapons. "They want to kill the Buddhists so that these provinces can be Muslim," explains village chief Boonserm Petchuan. The minority Buddhist population in the South feels abandoned. Everyone lives in fear of the insurgents. But no-one knows who's behind the uprising. Prime Minister Thaksin has ordered the army to be more aggressive in rooting out rebels. But a backlash could drive thousands more into insurgency
