North Korea’s state-run Korean Central News Agency reported Monday that the North’s National Defense Commission has condemned the South Korean government for demanding apologies for North Korea’s provocations last year.

The commission released a statement saying that it will cut off inter-Korean military communication lines and will close its liaison office in the Mount Geumgang resort area.

The statement also said that it will put an end to what it says is the South Korean government’s instigation of conflict by carrying out ruthless actions against the South.

The commission also threatened to retaliate physically on any targets at any time in response to the South's psychological warfare as it has warned before.

A South Korean Unification Ministry official said that the ministry does not believe cutting off contacts in the East Sea and in the Mount Geumgang resort will have heavy impact on inter-Korean relations and that the South does not intend to respond for now.
