AN Afghan government official said a tentative agreement was reached Wednesday to transfer a detained Afghan Taliban military leader from Pakistan to Afghanistan, but Pakistan quickly denied the assertion. An Afghan Interior Ministry spokesman Zemeri Bashari told CNN that Mullah Abdul Ghani Baradar is to be handed over to Afghanistan as part of a prisoner swap between the two countries. The agreement, reached in Islamabad, still needs to be reviewed by legal authorities in both countries, and once theyve signed off on it, the exchange will start, Bashari said. However, Pakistans Interior Minister Rehman Malik told CNN there is no agreement to hand over Baradar as part of a prisoner swap and Afghanistan has not made a formal request for Baradar to be extradited. No such agreement has been reached between the two governments and no formal request has been received for the handing over of Mullah Baradar by the Pakistani government, he said. A prisoner swap was discussed but the Afghan Taliban we arrested are not prisoners. They have been detained and are being interrogated. We are examining if theyve committed any crimes in Pakistan. Once theyve gone through the legal scrutiny in Pakistan then we will consider any requests by the Afghan government to hand them over.
