SEOUL, Jumada I 24, 1437, March 04, 2016, SPA -- North Korean leader Kim Jong Un ordered his country to be ready to use its nuclear weapons at any time and to turn its military posture to "pre-emptive attack" mode in the face of growing threats from its enemies, official media said on Friday, according to Reuters. The comments carried by official KCNA news agency marked a further escalation of tension on the Korean peninsula after the U.N. Security Council imposed harsh new sanctions against the isolated state for its nuclear programme. Kim made the comments as he supervised the exercise of newly developed multiple rocket launchers, KCNA reported. It did not mention the date of the drills but said the new weapons had South Korea within range. --SPA 03:02 LOCAL TIME 00:02 GMT www.spa.gov.sa/w
