North Korea launches ballistic missiles toward sea ahead of South Korean leader's visit to China

South Korea says North Korea has launched ballistic missiles toward the sea. South Korea’s Joint Chiefs of Staff says it detected several ballistic missile launches from North Korea’s capital region Sunday morning, hours before South Korea’s president left for China for talks. It says the missiles were fired toward North Korea’s eastern waters. Experts say North Korea is likely ramping up weapons tests to show off its achievements ahead of its ruling Workers' Party congress. Observers are watching the congress to see whether North Korea will set a new policy on the U.S. and respond to its calls to resume long-stalled talks.
