A roadside bomb today killed at least seven Pakistani security men in the country's Khyber tribal agency. Local officials said a convoy of the Frontier Constabulary was traveling from a fort when the bomb was detonated through a remote control at Sur Ghar area, bordering Afghanistan. Officials said 15 other security men were injured and were taken to hospital in Peshawar. No group has claimed responsibility but the Pakistani Taliban regularly target security men in the region.
