He also admitted that Pakistani tribesman near the border were support attacks by Taleban insurgents in Afghanistan and vowed to crack down.
The gathering of more 600 Pakistani and Afghan tribal leaders was organized to come up with solutions to growing violence and instability on both sides of the border.
