Three foreign contractors have been killed when an Afghan dressed in police uniform opened fire at a police training camp in the western province of Herat, the International Security Assistance Force (ISAF) press desk has said.
"An individual wearing an Afghan National Army uniform turned his weapon against International Security Assistance Force contracted civilian employees in western Afghanistan today, killing three," the ISAF said in a statement on Saturday.
The individual who fired on the contracted civilian employees was killed following the engagement, ISAF said.
