MOSCOW (Sputnik) — The missile has a range of at least 500 kilometers (310 miles), Yonhap news agency reported. President Park Geun-hye personally oversaw the launch.
Seoul plans to deploy the new missile by the end of this year, the media outlet reported.
Last month, North Korean state media announced that Pyongyang had carried out a ballistic missile launch from a submarine. Subsequent examination of alleged altered photographs documenting the launch caused many experts to claim the event never happened.
Later that month, Pyongyang announced that it had produced "mini-nukes" and increased the target accuracy of its long-range missiles.
The Korean peninsula formally remains in a state of war since the 1950-1953 Korean War ended in an armistice, but not a final peaceful settlement.
