Thai language curriculum to the exclusion of the region's Patani-Malay languages, a policy which produces low literacy rates and contributes to the view of government schools as antagonistic to Malay culture. The secular educational system is being undermined by the destruction of schools and the murders of teachers by the insurgent groups. The lesser educated Muslims also have reduced employment opportunities compared to their Buddhist neighbours. Only 2.4% of all working Muslims in the provinces held government posts, compared with 19.2% of all working Buddhists. Jobs in the Thai public sector are difficult to obtain for those Muslims who never fully accepted the Thai language or the Thai education system. Insurgent attacks on economic targets further reduce employment opportunities for both Muslims and Buddhists in the provinces. Leading insurgent groups Currently the most active insurgent movements are the BRN-Coordinate, its alleged armed wing the Runda Kumpulan Kecil (RKK), and the GMIP. PULO, the doyen of the Patani insurgent groups and formerly the most respected secessionist movement in the region, has been largely inactive in recent years. BRN-C The Barisan Revolusi Nasional-Koordinasi (BRN-C) is currently the most important group, spearheading the insurgency in southern Thailand. It was revived after 2001 and its leaders are mainly Salafi religious teachers who have rejected the Pan-Arab socialist ideology of the early BRN, engaging in political activism by recruiting followers in mosques and indoctrinating at Islamic schools. This group has the vision of becoming a mass movement, aiming towards having 400,000 members in its area of operation. The BRN-C has no constructive cultural or nationalistic goals; instead its immediate aim is to make southern Thailand ungovernable. It has been largely successful at spreading and maintaining an atmosphere of terror and uncertainty through well-trained secret militant units that engage in assassinations and calculated destruction. RKK The Runda Kumpulan Kecil (RKK), allegedly one of the armed wings of the BRN-C, has been one of the most brutal and ruthless groups of the south Thailand insurgency in recent years. It is composed of young, mostly Salafi, militants who routinely flee to Malaysia after carrying out violent attacks, including bombings, arson, and murders in Yala, Pattani, or Narathiwat Province. Although several RKK members have been arrested or killed by the Thai military in the past decade, it is difficult for those involved in counter-insurgency to penetrate the structure of the group owing to its secrecy and mobility.
