North Korean leader Kim Jong Un has supervised a fresh test of a “super-large multiple rocket launcher” system, state media said yesterday -- the latest in a series of provocations by Pyongyang. South Korea’s military said Tuesday that the North had launched “unidentified projectiles” from the Kaechon area in South Pyongan province. They flew approximately 330 kilometres (205 miles). The launch came shortly after Pyongyang said it was willing to hold working-level talks on denuclearisation later this month with the United States. Kim “gave field guidance” for Tuesday’s test, the Korean Central News Agency reported. The “super-large multiple rocket launcher” was tested in an exercise observed by Kim about two weeks ago.
