Two Taliban insider attack facilitators have been killed in eastern Afghan province of Kunar, the NATO-led coalition forces confirmed on Monday.
"Afghan and coalition forces confirmed today the death of the two Taliban insider attack facilitators, Mahmood and Rashid, during a security operation in Ghaziabad district, Kunar province, Wednesday," said the International Security Assistance Force (ISAF) in a press release.
Mahmood was responsible for the death of one American service member during the May 11, 2012, insider attack in the province 180 km east of Afghan capital Kabul, the press release said.
"Rashid was Mahmood's associate and a former Afghan National Army (ANA) soldier who facilitated and assisted with insider attack planning and execution," it noted.
The coalition military officials have recently said that about 25 percent of the so-called "green-on-blue" insider attacks are in some manner related to the Taliban-led insurgency. They said the factors that contribute to the so-called green on blue shootings are wide-ranging from infiltration and impersonation to personal grievances.
More than 60 U.S. and NATO soldiers were killed in 45 green-on- blue attacks last year, according to coalition officials. So far this year, One British service member was killed in such attack in the country's southern province of Helmand.
The Taliban insurgent group, which has been waging an insurgency of more than one decade, has yet to make comments.
