An American serviceman was shot and killed by a Honduran soldier during joint maneuvers in Honduras, U.S. military sources said. The name of the U.S. soldier is being withheld pending notification of next of kin, the sources said. The shooting occurred near Juticalpa, about 125 miles east of Tegucigalpa, the U.S. sources said. Military officials from both countries are investigating the circumstances around the shooting. It is believed to be the first case in which an American serviceman was killed by a Honduras soldier since the two countries began holding maneuvers in 1982.
