Afghan and NATO officials say an Afghan policewoman has killed a foreign adviser in the capital.

Authorities say the police officer killed the adviser Monday in Kabul's police headquarters.

Officials say the shooting is an apparent “insider attack” in which Afghan forces turn their weapons on a member of the Western coalition with whom they have been working.

The incidents have undermined trust between coalition and Afghan forces who are under mounting pressure to contain the Taliban insurgency before most NATO combat troops withdraw by the end of 2014.
