Pakistani President General Pervez Musharraf is sure that Osama Bin Laden is not only alive, but is residing in the Pak-Afghan tribal area. "Osama is alive and I am cent percent sure that he is hiding in Pak-Afghan tribal belt", Online News quoted him as saying during an interview with CNN, which is due to be telecast on Saturday. The impassable mountain ranges, where he thinks Osama is, would make it very tough to locate him due to the rugged nature of the terrain and the poor communication infrastructure existing therein. "Government is developing this infrastructure to hunt down Osama and cleanse the area from remnants or Al-Qaeda", he added.
