US soldier who crossed into North Korea faced disciplinary action back home

The U.S. soldier who on Tuesday crossed into North Korea during a civilian tour of the border zone had been due to face disciplinary action by the U.S. military, two U.S. officials told Reuters, speaking on condition of anonymity.

It was not clear how the soldier arranged to participate in tour. A third U.S. official said the soldier had crossed into North Korea "willfully and without authorization."
