At least 14 people were killed Monday when a suicide bomber drove a bike laden with explosives into a patrol of Afghan and international forces. Three of the dead were NATO soldiers.

"I heard the explosion and came right to this area. I saw the dead bodies of policemen and of civilians right here," policeman Hashmat Khan said.
    
The Taliban has claimed responsibility for the attack.

U.S. forces became embroiled in a firefight with their Afghan army allies over the weekend, leaving two more American soldiers dead.

The latest insider attack raised the U.S. death toll to 2,000 over the course of the 11-year war in Afghanistan.
