SEOUL, South Korea (AP) — North Korea has launched a short-range ballistic missile toward the sea as it ramps up testing activities in response to ongoing U.S.-South Korean military drills. South Korea’s Joint Chiefs of Staff says the missile launched Sunday morning from the North’s northwestern region flew across the country before it landed in the waters off its east coast. The launch was the North’s third round of weapons tests since the U.S. and South Korean militaries began joint military drills last week. The North views such drills as an invasion rehearsal. The chief nuclear envoys from South Korea, Japan and the U.S. condemned the launch as a provocation that threatens peace on the Korean Peninsula and in the region.
