US boosts intelligence after Afghan insider attacks

WASHINGTON - The Pentagon said on Tuesday it was expanding counterintelligence staff in Afghanistan after a rise in insider attacks by Afghans thought to be friendly to US forces but who have killed 37 coalition troops so far this year.
Last Friday, six US troops were killed in two separate incidents, one which saw an Afghan police commander and several of his men kill three US Marines after inviting them to a Ramadan breakfast to discuss security.
Defense Secretary Leon Panetta said he was deeply concerned by the killings "because of the lives lost and because of the potential damage to our partnership efforts."
