KABUL, Afghanistan (AP) — A person wearing an Afghan national security force uniform turned his weapon Sunday against civilian contractors with the U.S.-led military coalition, killing three.
In other incidents, five NATO service members were killed in roadside bombings over the past two days.
NATO said the attack on the civilian coalition workers occurred in western Afghanistan but disclosed few other details.
The gunman was killed during the incident, which is still being investigated. No further information about the civilians who died was released.
Afghan security forces or militants dressed in their uniforms have been killing a rising number of coalition forces, but they have not been specifically targeting contractors working for the coalition. So far this year, 26 foreign troops have been killed in this type of attacks.
In other violence, a spokesman for the governor of eastern Wardak province said insurgents had kidnapped five Afghan men working a base jointly operated by Afghan and NATO forces and killed them. Spokesman Shahidullah Shahid said their bodies were discovered early Sunday.
Also Sunday, Afghan officials reported that four civilians died when hundreds of shells and rockets were fired from neighboring Pakistan.
The artillery shells hit homes along frontier areas from which insurgents have in the past staged cross-border attacks.
There is little or no Afghan or NATO military presence in the area and large swaths of the region are controlled by insurgent groups. The information could not be independently verified because the area is largely off-limits to reporters.
The Afghan government has not openly blamed the Pakistani military for the artillery barrage, which reportedly hit districts in the eastern provinces of Nuristan and Kunar. Both are considered insurgent hotbeds, and militants allied with both the Afghan and Pakistani Taliban regularly cross the mountainous border in both directions.
