Three NATO Troops Killed by Man in Afghan Uniform
34 "insider attacks" so far this year
The U.S.-led military coalition in Afghanistan says three of its troops have been killed by a man in an Afghan army uniform.
The attack is the latest in a rising number of disturbing shootings this year by Afghans soldiers -- or insurgents dressed as government troops -- on the international forces training them to fight the Taliban as the international coalition withdraws.
