KABUL, Oct. 26 (Xinhua) -- The Taliban militants on Friday claimed responsibility for an attack carried out by a man wearing the uniform of Afghan police in southern Uruzgan province.
Zabihullah Mujahid, who claims to speak for the armed outfit, told local media that the attacker was a Taliban loyalist who infiltrated into the ranks of Afghan security forces to kill foreign troops.
The NATO-led coalition forces also confirmed in a statement issued late Thursday that a man wearing an Afghan National Police (ALP) uniform turned his weapons against coalition forces in the province, 370 km south of Kabul, the latest in the so-called green- on-blue attack when Afghan army, police or gunmen in their uniform open fire against their international partners.
"Two U.S. Forces-Afghanistan service members died after an individual wearing an Afghan National Police uniform turned his weapon against them in Khas Uruzgan, Uruzgan," the coalition statement said.
The brief statement did not provide details about the incident, only saying "The incident is currently under investigation."
At least 55 foreign troops have been killed in 35 green-on-blue insider attacks so far this year.
Such attacks also claimed the lives of more than 50 Afghan police and army since beginning this year.
As the Taliban claimed responsible for the Thursday's attack, the coalition military officials have recently said that about 25 percent of the insider attacks are in some manner related to the Taliban-led insurgency.
They said the factors that contribute to the green-on-blue shootings are wide-ranging from infiltration and impersonation to personal grievances. However, it is said that the cultural differences between Afghan security forces and their western partners could also be a reason for the attacks.
A total of 50 countries are contributing 100,000-strong forces in Afghanistan with over 68,000 of them American mainly stationed in the east and south, followed by 9,500 from UK mainly based in southern Afghanistan.
More than 360 foreign soldiers have lost their lives in Afghanistan since January this year.
