The US Army has identified the soldier who crossed the demarcation line into North Korea on Tuesday as Pvt.

US military officials say King “willfully and without authorization” crossed into North Korea while taking a civilian tour of the Joint Security Area, a small collection of ​buildings inside the 150-mile-long demilitarized zone (DMZ) that has separated North and South Korea since the end of the Korean War in 1953.

“We believe he is currently in (Democratic People’s Republic of Korea) custody and are working with our (Korean People’s Army) counterparts to resolve this incident,” US Forces Korea spokesperson Col. Isaac Taylor said in a statement.
