U.S. Service Member Killed, Two Wounded in Afghanistan During Apparent Insider Attack

One U.S. service member was killed and two others wounded Saturday in an apparent "insider attack" in southern Afghanistan, making it the first attack of its kind on U.S. personnel this year.

The wounded service members are in stable condition and are receiving treatment, according to the NATO Resolute Support, a NATO-led coalition that aids Afghan security forces.

The name of the killed soldier has not been released.

There were 47 "green-on-green" attacks, when Afghan security forces are attacked from within their own forces, from December 1, 2017 through May 31. There were no insider attacks on U.S. service members during the same period, according to a Department of Defense (DoD) report released last month.

Insider attacks on Afghan forces – and deaths resulting from those attacks – have increased by more than 50 percent compared to the same time frame last year. The DoD report also said that NATO Resolute Support advisers are working to require better national screening for Afghan security forces personnel.

The last insider attack that resulted in a U.S. casualty occurred in June 2017, according to NATO Resolute Support officials.

Since U.S. involvement in Afghanistan began in October 2001, 1,876 U.S. military personnel have been killed in action and 20,385 have been wounded in action, as of May 31. In the six months prior to June, there were two U.S. military deaths due to hostile actions and 22 U.S. military personnel wounded, according the DoD report.
