The U.S. and South Korean held joint live-fire military drills in response to Pyongyang's longest-range ballistic missile test that caused alarm in Japan as it flew over the country on Tuesday.
Driving the news: The U.S. Indo-Pacific Command tweeted that the exercises were designed to "showcase combined deterrent & dynamic strike capabilities" after the North Korean military's first missile launch over Japan in five years and its fifth test in just over a week.
