US, South Korea begin largest-ever joint air drill
The US and South Korea on Monday began their largest-ever joint air exercise. The five-day drill, which involves 230 aircraft and thousands of troops, comes days after North Korea test-fired its highest-ever intercontinental ballistic missile (ICBM). North Korea has labelled the drill as an "all-out provocation" and has accused the US of  "begging for nuclear war" by staging the exercise.
