Insurgents have killed 14 paramilitary soldiers in Pakistan\'s southwestern Balochistan province in attack on their check post, official sources said Wednesday. The Frontier Corps (FC) sources told correspondents in Quetta, the provincial capital, that 15 other soldiers were injured on the Tuesday\'s night attack in Sibi district. They said when the soldiers did not return to their barrack from a check post in Marawar area, some 40 kilometers from Quetta, in the evening, other soldiers went to the post. They found bodies and the injured lying in the check post, the FC sources said. No group claimed responsibility. The government blames suspected Baloch insurgents for attacks on security forces and government\'s installations. Baloch, insurgents, fighting for more rights, are active in the area. Sources said that a helicopter was sent to the area after the information was passed on to the authorities in Quetta last night. Bodies and the injured were airlifted to Quetta. Forces were sent to the area for a search operation in the region but no one has been arrested so far. Sources said that the attackers burnt the \"Khushdil Post\".
