Training operations for the Afghan Local Police, a security force separate from the Afghan National Police that operates in the more insecure and remote areas, has been suspended by the United States.
The suspension, affecting about 1,000 Afghans, comes in response to a recent rise in insider attacks in which coalition forces have been killed by Afghans in military or police uniforms.
There have been 34 friendly fire attacks this year - at least 15 in August alone - that have killed 45 international troops.
