Khyber Agency- At least three people have been injured in a blast in the Landi Kotal area of Khyber tribal region, say media reports today. Official sources say that the vehicle of Tawheed-ul-Islam peace committee activists was targeted in Landi Kotal’s Zakakhel area destroying the vehicle completely. The peace committee has suspected Lashkar-e-Islam militant group responsible for the attack. Meanwhile the Zakakhel tribesmen and the Afghan refugees living in parts of Bara tehsil have been warned by the Lashkar-i-Islam militant group to join them or leave the area. The Lashkar-i-Islam and Zakakhel tribesmen have been fighting for the last one year and renewed threats would further deteriorate the situation in the area. Khyber tribal area is a part of Pakistan’s semi -autonomous Federally Administered Tribal Areas (Fata) on the Afghan border. The Taliban and other Al Qaeda-linked groups, who stage attacks in both countries, are known to have strongholds in the zone.
