Narathiwat: Police have arrested two suspected bombers, thought to belong to the Runda Kampulan Kecil (RKK) insurgent group, who allegedly targeted an entourage of an organisation promoting peace in the deep South on Thursday. They were arrested yesterday in a pre-dawn raid on Hulupareh village in Rangae district by an 80-strong combined force. Police detained Udeeman Samoh, 21, and Sapee-aree Jehkor, 21, who are believed to have set off a 5kg bomb near Klong Tanyong bridge on Rangae-Cho Airong road on Thursday. The attack was reportedly aimed at members of the Independent Commission on Justice and Civil Liberties for the Southern Border Provinces who travelled past the bridge minutes before the blast. Nobody was injured. The team was headed by commission chairman Ukrit Mongkolnavin. Police said they seized one 11mm pistol and ammunition from the two suspects. Investigators said Mr Udeeman is a very skilful bomb-maker and belongs to the RKK. Mr Sapee-aree is considered one of the group's top members. In Pattani's Sai Buri district, meanwhile, police retrieved 11 assault rifles suspected to have been used in a recent insurgent attack on a military checkpoint in tambon Troh Bon. In Yala, four teenagers stormed a mobile phone shop in Muang district and made off with 30 SIM cards yesterday. Police believed it was the work of the Permudor, a local terrorist network. Elsewhere in Yala, separatist insurgents opened fire on a military outpost of the 534 special task force in Bannang Sata district yesterday. No injuries were reported.
