North Korea Test-Fires Submarine-Launched Ballistic Missile

SEOUL, South Korea -- North Korea on Saturday fired what appeared to be a submarine-launched ballistic missile off its east coast, the U.S. and South Korea said, the latest in a string of tests that are part of efforts by the North to advance technology capable of delivering nuclear warheads.
The missile was fired from a location near the North Korean coastal town of Sinpo, where analysts have previously detected efforts by the North to develop submarine-launched ballistic missile systems, said an official from Seoul's Defense Ministry. The official, who didn't want to be named because of office rules, couldn't immediately confirm how far the missile traveled or where it landed.
South Korea's Joint Chiefs of Staff said in a statement that it presumed the missile successfully ejected from the submarine's launch tube, but failed in its early stage of flight. South Korea's Yonhap news agency said that the missile likely flew only a few kilometers (miles) before exploding in midair, but the Defense Ministry official couldn't confirm the report.
The U.S. Strategic Command also said that the missile was tracked over the sea between the Korean Peninsula and Japan, where it apparently fell.
