Minju Joson Friday says in a bylined commentary in this regard:

This is a revelation of the bad habit of the puppets accustomed to totally denying and abusing what the DPRK says.

The situation in the Kaesong Industrial Zone (KIZ) is reaching the grave phase owing to the persistent and vicious acts and military provocations of the present south Korean authorities against the DPRK.

What they seek is to shift to the DPRK the blame for the crisis of KIZ whose operation had been kept even during the Lee Myung Bak regime and continue to perpetrate hostile acts and military provocations against it. But with nothing can they cover up their sinister intention.

If they truly want the crisis of KIZ to be solved, they should stop all the hostile acts and military provocations as demanded by the DPRK.

Doing so is a principled matter and prerequisite for solving not only the KIZ crisis but all other problems arising in the north-south relations. So, the DPRK will never hush up this matter.

If they intend to mislead public opinion with something like "incomprehensible" and "improper", KIZ will totally collapse and the traitors will never escape a stern judgement.
