There are, of course, well-organised militants in the South. AI: Southern Thailand separatist groups include the Barisan Revolusi Nasional (BRN), the Patani United Liberation Organization (PULO), and Gerakan Mujahidin Islam Patani (GMIP), which seek autonomy or independence for the Malay-Muslim majority provinces of Pattani, Yala, Narathiwat, Satun and parts of Songkhla. As ISOC has grown more repressive, enforcing curfews, policing mosques, political arrests, the violence against ISOC personnel has increased. PULO only blew up the train tracks--the visible reason Patani is oppressed--and gave lots of warning so no one was hurt.
