A spokesperson for the coalition said the troops died as the result of a vehicle-born explosive device near Bagram Airfield. Three NATO troops were injured, the spokesman added.
Further details on the circumstances of the attack and nationalities of those involved were not immediately available. Bagram is a large U.S. military base north of Kabul, the Afghan capital.
