(VOVworld) – The Republic of Korea reveals that the Democratic People’s Republic of Korea has threatened to launch surprise attacks in retaliation for anti-Pyongyang protests in Seoul early this week when Pyongyang was commemorating the death anniversary of leader Kim Jong Il.

North Korea’s National Defense Committee sent a fax to South Korean’s National Security Council on Wednesday using the military hotline on the western coast. The threat was issued following rallies in Seoul to protest the execution of Jang Song-Taek, an uncle of leader Kim Jong-un. Spokesperson of South Korea’s Defense Ministry, Kim Min-seok said Seoul sent immediate reply through the hotline, affirming that Seoul is closely following the situation and will strongly strike back against any provocation from Pyongyang.
