SEOUL, South Korea (AP) — North Korea launched a ballistic missile off its east coast on Monday, South Korea's military said, a day after the North vowed “offensive and overwhelming" responses to protest a new U.S. military drill with South Korea and Japan. The Joint Chiefs of Staff said the launch was made on Monday morning, but gave no further details, including how far the weapon traveled. The launch came two days after South Korea, the U.S. and Japan ended their new multidomain trilateral drills.
