N. Korea's liaison office in truce village caught fire: source
Built inside the Demilitarized Zone that separates the two Koreas in 1985, the North's conference hall, named "Tongilgak," is comparable to the Peace House in the southern portion of Panmunjom that serves inter-Korean dialogues and contacts.
North Korean leader Kim Jong-un visited the office and other conference venues in Panmunjom in March and ordered his military to keep vigilant for tight security on the frontier.
Internal maintenance works were underway inside the building at the time of the fire, the source said.
Seoul officials say the latest incident could be another sign of lax military discipline among North Korean troops as it came after a North Korean soldier reportedly shot and killed his platoon and squad leaders in a front-line unit before defecting to the South.
The two Koreas remain technically at war as the 1950-53 Korean War ended in a truce, not a peace treaty. (Yonhap)
