On Thursday, the Defense Department said that in order to blend in, special-operation forces often don the insignia of forces they accompany. On Friday, after Turkey complained, a spokesman called the action “unauthorized and inappropriate.”
A NATO spokesman on Monday identified the nationalities of the soldiers, but said he could not give further details on the incident because the matter was still being investigated, according to AP. The Taliban claimed responsibility for the bombing.
In addition to the six U.S. soldiers, bombs and attacks killed 16 Afghan civilians, five policemen and two members of the U.S.-led coalition on Sunday, according to NBC News.
