Six personnel of the khassadar tribal force were killed while four others were injured in an ambush by militants on their vehicle in Alamgodar area of Bara tehsil in Khyber agency. Pakistan forces cleared Khyber agency few months back but it seems that Bara tehsil is yet to be cleared from militants. The forces need to take stern action against the militants so that the locals have a healthy environment. We cannot ignore the fact that the militants are strong in the tribal belt and the government needs to establish its writ in that particular area as soon as possible.
