South Korea is considering all possible ways to hold North Korea accountable for demolishing the Gaeseong inter-Korean liaison office last week to protest against anti-Pyongyang leaflet campaigns in the South.

Unification Ministry spokesperson Yoh Sang-key, however, said Monday that there are legal challenges due to the special relationship between the two Koreas as they remain divided but are jointly striving for unification.

Following the destruction of the liaison office last Tuesday, Vice Unification Minister Suh Ho warned that Pyongyang will be held responsible for the latest provocation.

The ministry also urged the North to call off its planned delivery of propaganda leaflets to the South, stressing that the move harms the development of inter-Korean ties, and added that Seoul has outright banned similar activity in the South.
