North Korea has fired ballistic missile into sea, says South

Launch, possibly from a submarine, comes as US, South Korean and Japanese spy chiefs meet for talks in Seoul

North Korea launched a ballistic missile - possibly from a submarine - into the Sea of Japan, South Korea's military has said, in the latest in a series of tests by Pyongyang over recent weeks.

One ballistic missile was launched about 10:17am local time from the vicinity of Sinpo, South Korea's joint chiefs of staff said, where North Korea keeps submarines as well as equipment for test firing submarine-launched ballistic missiles (SLBMs).
