The group's passing penalties on the vice-chairman and the secretary general of the South Headquarters of Pomminryon is a treacherous anti-reunification act of hindering the national reconciliation and unity, the statement said.

Vice-Chairman Ro Su Hui's visit to Pyongyang was a very just act as he expressed deep condolences over the nation's greatest loss together with compatriots in the north, members of the nation, it noted.

The secretary general is in a critical condition as patient, it said, condemning the unwarranted judgment made by the court as a criminal act against human rights.

We will never pardon the Lee Myung Bak group which is making desperate efforts to escalate confrontation with the north and crack down on the reunification movement though it is inching close to the doom, the statement warned.

Justice is sure to win and the separatists are bound to be sternly judged by history for their crimes, it stressed.
