South Korea says North Korea has launched a ballistic missile toward the sea, the second such weapons testing activity by North Korea in less than a week. North Korea's launch events are likely a protest of the upcoming Korea-U.S. military drills that North Korea views as an invasion rehearsal. South Korea’s military says it detected the launch from North Korea’s eastern coastal Wonsan area around 6 a.m. The launch came two days after South Korea and the U.S. announced they will kick off their annual military drills next week to beef up readiness against North Korean threats.
