UN officials reported on Tuesday that a US citizen has entered North Korea from South Korea “without authorization.”
“A US national… crossed, without authorization, the Military Demarcation Line into the Democratic People’s Republic of Korea (DPRK),” said United Nations Command overlooking the Joint Security Area in the Demilitarized Zone (DMZ) between South and North Korea.

“We believe he (the US national) is currently in DPRK custody and are working with our KPA (North Korean People’s Army) counterparts to resolve this incident,” the UN command said on Twitter.
