Kim Jong-un oversees missile launch to strengthen North Korea's maritime borders. The leader expressed "great satisfaction with the results of the shooting," KCNA added.
The missiles reached their targets after flying over the East Sea for 1,400 seconds. North Korea also announced on Monday that it had developed a new control system for multiple rocket launchers that it believes could significantly strengthen its defense capabilities. The maritime border between the two countries, known as the Northern Boundary Line, has never been officially demarcated and has been the scene of previous clashes.
