Washington, Mar 7 : The main reason behind the growing strength of insurgency in Afghanistan is due to al Qaeda and Taliban militants finding safe havens in Pakistan and the surging output of jihadis from radical Islamic schools, according to Canadian Defence Minister Peter Mackay.

"The Taliban are growing in strength because they have the ability to seek safe haven in Pakistan," Mackay said about the source of the growing Afghan insurgency lies across the border in Pakistan.
