WASHINGTON (Reuters) – A U.S. soldier has crossed the inter-Korean border into North Korea, two U.S. officials told Reuters on Tuesday, speaking on condition of anonymity.

One of the officials said the soldier was believed to be in North Korean custody. The officials did not immediately offer further information.

The United Nations Command that oversees the demilitarised zone area at the border earlier on Tuesday identified the individual as a U.S. national but offered no further details about their identity.
