As the unidentified man tried to cross the Imjin River near the western border in Paju, north of Seoul, at around 2:23 p.m., (0623 GMT), soldiers fired off warning shots and told him to return to the South. When he disobeyed the order and jumped into the river, an Army corporal shot him dead, the Joint Chiefs of Staff said. A special team was formed to investigate the incident, and an investigation was under way to determine the man\'s identity and his motive for the border crossing, military officials were quoted as saying.
