Karzai said in recent fighting in the Garmser district of Helmand province - where hundreds of U.S. Marines have been battling insurgents the last two months - that most of the fighters came from Pakistan.

Karzai called Pakistan a "brother government" and "friend," but also urged it to "act against those elements that are making Pakistan and Afghanistan insecure." He said it was better for Afghan troops to be killed during offensive operations into Pakistan than in militant attacks in Afghanistan.

His comments come as Pakistan is seeking peace deals with militants in its borders, including with Mehsud.

The deals have come under criticism from U.S. officials, who warn they will simply give militants time to regroup and intensify attacks inside Afghanistan. But Pakistan insists it's not negotiating with "terrorists," rather militants willing to lay down their arms.

Karzai is talkative and good for nothing
