N. Korea Faxes Threat to South Warns it will strike 'without notice' after rallies held in Seoul By Kate Seamons, Newser Staff Posted Dec 20, 2013 2:00 AM CST Updated Dec 20, 2013 5:29 AM CST 26 comments Comments A portrait of North Korean leader Kim Jong Un is burned by protesters during an anti-North Korea rally marking the second anniversary of former North Korean leader Kim Jong Il's death in Seoul, South... (AP Photo/Ahn Young-joon) (Newser) – North Korea has issued quite the threat to South Korea ... via fax. Yonhap reports that the North's National Defense Commission yesterday faxed the South's National Security Council, and its message contained a threat to strike the South "without notice." Yonhap explains that the fax followed a number of rallies in Seoul on Tuesday, attended by North Korean defectors as well as South Koreans, in protest of North Korea. Spotted there: Kim Jong Un's burning photo. (This on the same day that the North marked the second anniversary of Kim Jong Il's death.) The North swung at the rallies for insulting its "highest dignity" (that's Kim Jong Un), and the South wasted no time in responding, saying it would "sternly react" to any such action.
