North Korea is demolishing a South Korea-built property that had been used to host reunions of families separated during the 1950-53 Korean War, the South’s government said Thursday, as it continues to eliminate symbols of engagement between the war-divided rivals.

North Korea is dismantling a facility at its Mount Kumgang resort used for hosting meetings between families separated after the Korean War, South Korea said on Thursday, in the latest sign of strained tensions between the two Koreas.

South Korea condemned North Korea’s demolition of a 12-story resort where families separated by the Korean War held brief reunions, calling the action “an act against humanity.”

Representatives from two Western travel agencies crossed into North Korea Thursday for the first time since the isolated regime closed its borders five years ago, raising hopes for new tour offerings to a border city.

A remote part of North Korea is set to reopen to tourists this month, the first organised tour open to international visitors since the country’s borders closed in January 2020.

North Korea closed its borders five years ago when the COVID-19 pandemic hit, and they have remained shut ever since.
