The DPRK urged the Neutral Nations Supervisory Committee to secure the immediate release of North Korean pilot, who crash landed with MIG-15 on 3 December 1970. Their appeal is due to the failure of UN Command-DPRK talks on the matter. Additionally, the hijacking of KAL plane F-27 on 23 January 1971 by a South Korean youth has been attributed to "North Koreans' underground activities."
