S Korea tests submarine-launched ballistic missile after N Korea fired 2 missiles

South Korea on Wednesday successfully tested a submarine-launched ballistic missile (SLBM). South Korea's missile test came the same day as North Korea fired two ballistic missiles into the sea. President Moon Jae-in attended the underwater ejection test of the SLBM aboard the new 3,000 ton class Dosan Ahn Chang-ho submarine commissioned last month.
