South Korea and US test defences against North Korea

South Korean and US troops have begun large-scale military exercises, in an annual test of their defences against North Korea.

The latter called the drills “nuclear war moves” and threatened to respond with an all-out offensive.

South Korea said the exercises would be the largest ever, following North Korea’s fourth nuclear test, in January, and a long-range rocket launch last month, which triggered a UN Security Council resolution and tough new sanctions.
