1 killed in Afghan insider attack

A coalition contractor in eastern Afghanistan was killed Friday when people wearing Afghan National Army uniforms turned their weapons against International Security Assistance Force members, ISAF said.
The coalition has been working to thwart "insider" or "green-on-blue" attacks -- strikes against coalition members by people clad in police or army uniforms.
The nationality of the ISAF-contracted civilian has not been released. The incident is currently under investigation.
