Afghan and NATO officials say a female Afghan police officer has killed an American civilian adviser in the capital.

Authorities say the policewoman killed the U.S. adviser Monday inside Kabul's heavily guarded police headquarters. Officials say she was arrested by Afghan forces after the incident.

Media reports say the suspect is a policewoman named Nargis who works in the Legal and Gender Equality Department at the Interior Ministry.

Officials say the shooting is another “insider attack” in which Afghan forces turn their weapons on a member of the Western coalition working with Afghan units. The suspect would be the first woman to carry out such an attack.

The shooting in the capital was one of several in Afghanistan Monday. NATO says a coalition service member was killed in an insurgent attack in eastern Afghanistan. In northern Afghanistan, officials said an Afghan police officer shot five of his colleagues at a checkpoint in Jawzjan province. A Taliban spokesman told the BBC that the police officer had been a Taliban infiltrator for some time.
