One soldier was killed and two injured when a roadside planted explosive device went off on Tuesday here close to Amin check-post. Official sources said that as curfew was imposed on the route from Miranshah to tehsil Dattakhel area of North Waziristan Agency for the movement of military convoys in the rugged region, roadside planted explosive device detonated, targeting army vehicle when military convoy was on move. Resultantly, one solider was killed at the spot and two others injured. The injured were immediately rushed to hospital for treatment. Security forces cordoned off the entire area and started search to nab the culprits but till last updates no arrest was made. It is pertinent to mention here that local administration imposes curfew twice in a week on both the routes from Miranshah to Dattakhel and from Mirali to Miranshah to ensure smooth movement of the military convoys but repeatedly many personnel were killed in the roadside bombings in the rugged region bordering Afghanistan.
