一名阿富汗士兵打死两名北约军人

NATO officials in Afghanistan say an Afghan National Army soldier has turned his weapon on two of the coalition's service members, killing them.  

NATO says its troops returned fire, killing the soldier.

The attack Monday in eastern Laghman province is the latest in a string of insider attacks this year.

In another development, officials in southern Afghanistan say Taliban insurgents have beheaded 17 Afghan civilians.

The Associated Press reports the victims in Helmand province had gathered for a celebration and were playing music and dancing. The Taliban does not approve of such activities.
