The militant attack took place on Wednesday when a car bomber hit US-led forces’ a convoy in Bati Kot district in the east of Nangarhar Province in Afghanistan, a Press TV correspondent reported.
Taliban spokesman has claimed responsibility for the attack. NATO has yet to confirm the attack.
The Taliban are stepping up their attacks on foreign forces across war-ravaged Afghanistan.
Over 1,400 American soldiers have been killed in Afghanistan since the US-led invasion of the Asian country began in 2001, according to a recent report by the Associated Press.
In 2010, as many as 711 foreign troops lost their lives in Afghanistan — an average of two a day — which is by far greater than the previous record annual toll of 521, marked in 2009.
Despite the presence of about 150,000 foreign troops in Afghanistan, insecurity is on the rise across the country since the US-led war began there in 2001
