Suspected militants have kidnapped 17 Pakistani policemen from posts on the Khyber Pass, the latest security incident on the vital supply route for Western forces in Afghanistan. Militants attacked four checkposts on Sunday night on the winding road through the pass which leads to the Afghan border, kidnapping the policemen and wounding one in a brief exchange of fire, a senior government official in the region said. "Our 17 khasadar are missing," said the official in Landikotal, the main town in the Khyber region, referring to members of special police forces recruited in ethnic Pashtun tribal agencies. "The attackers appear to be outsiders, maybe militants from Mohmand," the official was quoted as saying by Reuters.
