ISLAMABAD: Unidentified men fired rockets at a Frontier Corps (FC) camp near Mach in Balochistan on Monday. There were no immediate reports of casualties. Separately, unidentified people booby-trapped an electricity pylon and blew it up, suspending electricity to the Mach area for two hours. An FC official said, "Unidentified people fired about six rockets at an FC camp from the National Highway, which missed their target and hit the hills around the camp." FC and Levis personnel retaliated and the attackers took flight. Earlier, 10 hostages held by tribesmen in Balochistan were freed by security forces, the Balochistan home minister said. They were abducted on Tuesday from the Sui gas fields after several days of clashes between security forces and tribesmen. On Friday, the Balochistan government asked the federal government to take charge of security at the Sui gas plant.
