15 Pakistani prisoners released by Afghan authorities were being held in Landi Kotal Jail for debriefing, official sources told Daily Times. The prisoners, handed over to Pakistani authorities on Saturday night at the Torkham border from the Afghan Pull Charkhi Jail, were shifted to Peshawar Central Jail from various jails in the Khyber Agency. Officials said the prisoners would be released following the debriefing process. Interrogation of the prisoners might reveal more information regarding the whereabouts of various extremist and terrorist organisations in the country, sources said.These prisoners had moved to Afghanistan in 2001 to fight alongside the Taliban against US-led allied forces, but were eventually captured by the American and Northern Alliance forces in Afghanistan. The prisoners belong to different districts of Punjab, Sindh and NWFP. Seven of them are from the Malakand Division, two from Karachi and one each from Sargodha, Khanewal, Mandi Bahauddin, and Islamabad.
