North Korea Detains US Soldier Who Faced Expulsion

An American Cavalry scout, recently released from prison in South Korea, fled a South Korean airport to join a private tour and crossed into North Korea. This unauthorized crossing marks the first American detained in North Korea in nearly five years. The incident recalls the 2017 case of US student Odo Warmbier, who died after 17 months in North Korean captivity. Tensions are rising again along the Korean border, 70 years after the Korean War ended.
