An American national who entered North Korea "without authorization" during a tour of the heavily fortified border and is believed to be detained is a US soldier, officials said Tuesday.

North and South Korea remain technically at war since the 1950-1953 Korean War ended with an armistice rather than a peace treaty, with a Demilitarized Zone running along their border.
"A US service member on a JSA orientation tour willfully and without authorization crossed the Military Demarcation Line" into North Korea, spokesman Colonel Isaac Taylor said in a statement, referring to the Joint Security Area north of Seoul.
A US official previously told AFP on condition of anonymity that the American national was a soldier who is now believed to be in North Korean custody.

CBS News reported that the soldier was a low-ranking member of the US Army who was being escorted home to the United States for disciplinary reasons, but somehow managed to leave the airport and join the tour group.
