The Afghan government says it has reached an agreement with the United States that will govern NATO's controversial night raids on Afghan homes.

Afghanistan says the deal will result in foreign forces having only a supporting role in the night-time operations, which will be led by Afghan troops.

The foreign ministry says Afghan Defense Minister Abdul Rahim Wardak and the commander of U.S. forces in Afghanistan, General John Allen, will sign the agreement Sunday.

The U.S. has not commented on the deal.

Night raids have been a constant source of tension between the Afghan government and the U.S. military.
