SEOUL (Reuters) - North Korea appeared to conduct a submarine-launched ballistic missile test on Saturday but it ended in failure with no indication that the missile successfully ejected from the vessel and took off, South Korea's Yonhap news agency reported.
The test, if confirmed, follows a test-launch in May of a submarine-launched ballistic missile (SLBM), which Pyongyang boasted as a success but has not been independently verified.
