Seoul: North Korea says its new leader, Kim Jong Un, has ordered troops to launch a powerful retaliatory strike against South Korea if provoked.
The official Korean Central News Agency reported on Sunday that Kim issued the order during a visit to front-line military units, including one that shelled South Korea`s Yeonpyeong Island in 2010, killing four people.
South Korean and US troops are to kick off annual computer-simulated war games Monday. North Korea has threatened a "sacred war" over the drills.
A senior US envoy said Saturday that ties between the two Koreas need to improve before North Korea and the United States can achieve real progress in their relationship.
