Mellissa Fung swapped for prisoners?

Canadian Prime Minister Stephen Harper denied Mellissa Fung, the CBC journalist kidanpped by the Taliban a month ago, was released in exchange for Taliban leaders at the weekend,

“There have been continual reports about ransoms or money being paid. That was not done in this case,” he told reporters in Ottawa following a first ministers meeting. There has been no release or exchange of political prisoners. This matter is being handled according to the laws of the Government of Canada, the Government of Afghanistan, and that’s all I’ll say on that regard.” link

The denial comes after the Pakistan Observer reported the prisoner swap claims yesterday.
