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.
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.
