KABUL: An Afghan in police uniform shot and killed a Nato soldier in southern Afghanistan on Sunday, the military said — taking the death toll from insider attacks this year to 40.

“An International Security Assistance Force service member died when an individual wearing an Afghan Uniformed Police uniform turned his weapon against Isaf service members in southern Afghanistan today,” Isaf said.

Afghan and Isaf officials were investigating the incident, a statement said without giving further details or specifying the soldier's nationality.
