NATO said Wednesday that several of its troops have been shot and wounded by a man in an Afghan Army uniform. According to a statement, the NATO troops were being treated at a medical facility in the Sayed Abad district of Afghanistan's eastern Wardak province at the time of the attack. This incident is just the latest insider attack on NATO troops (an Afghan policeman killed three British soldiers last weekend) bringing the total number of attacks by Afghan security officials on NATO troops this year to 18.
