SEOUL, South Korea (AP) — South Korea and the United States on Monday began their annual joint military exercises, but they paused live-fire training while Seoul investigates how two of its fighter jets mistakenly bombed a civilian area during a warm-up drill last week.

North Korea's state media on Tuesday ramped up criticism against joint military drills by South Korea and the United States, calling them a "nuclear war exercise," but made no mention of the North's ballistic missile test a day earlier.
