U.S. Defense and military officials said more than a dozen Western soldiers in all, including several Americans, were shot as high-level officials visited the heavily guarded military complex.
A lone gunman dressed in an Afghan army uniform opened fire with an automatic weapon during a meeting at the Afghanistan National Military Academy, located at the Marshal Fahim National Defense University in Kabul.
Officials also said the death toll is expected to rise given the severity of troops' injuries.
