A roadside bomb blast struck NATO soldiers patrolling in eastern Afghanistan, killing two of the troops and wounding one other, AP reported. The soldiers were conducting a routine patrol on Tuesday when they bomb went off in the Sharan district of Paktika province, said NATO's International Security Assistance Force. ISAF did not provide the nationalities of the soldiers. The latest casualties brings the number of foreign troops killed in Afghanistan to 21 so far this year. In 2007, insurgency-related violence killed more than 6,500 people, including 222 foreign troops. Last year was the deadliest yet since the U.S.-led invasion in 2001.
