A man wearing an Afghan military uniform was killed Saturday after attacking but failing to harm members of a coalition force in Afghanistan, officials said. The attack against members of the International Security Assistance Force took place in eastern Afghanistan, CNN reported. A military spokesman said the gunman was killed and there were no ISAF casualties. So-called insider, or green-on-blue, attacks on NATO-led troops have led to U.S. commanders ending some joint operations with Afghan forces.
