WASHINGTON (AP) -- The Associated Press has learned that a U.S. military investigation is recommending that as many as seven U.S. troops face administrative punishments, but not criminal charges, in the burning of Qurans at a U.S. base in Afghanistan in February.

U.S. military officials say the classified report and recommendations for disciplinary action against the service members involved were delivered to the Pentagon more than a week ago. No final decisions have been made.

Several Qurans were thrown into a garbage fire pit, setting off riots among Afghans.

U.S. officials say one Navy service member and as many as six Army soldiers face punishment that can range from a letter in their file to docking their pay. .

U.S. military officials spoke on condition of anonymity because the matter is under review.
