South Korea's military expressed deep concern about the Democratic People's Republic of Korea (DPRK) test-firing a ballistic missile from its submarine.
"Our military is deeply and seriously worried about the underwater test-firing of a ballistic missile conducted by North Korea (DPRK) last week," Defense Ministry spokesman Kim Min-Seok said, Xinhua reported.
The DPRK's news agency reported Saturday that it successfully test-fired a ballistic missile from a submarine which was supervised by top leader Kim Jong-un.
Kim urged Pyongyang to stop developing the submarine-launched ballistic missile that according to him would destabilize the Korean Peninsula and the Northeast Asian region.
