South Korea, US, Japan hold missile defence drills to counter North Korea

South Korea, the United States and Japan staged joint naval missile defence exercises on Monday, in a push to improve security co-operation and respond
better to North Korea’s evolving missile threats, Seoul’s navy said.
The news came days after the three nations agreed at talks in Washington to hold regular missile defence and anti-submarine exercises in their efforts to boost diplomatic and military co-operation.
Tension has simmered in recent weeks as the North ramped up military activities, testing a new solid-fuel intercontinental ballistic missile on Friday that experts say would ease the way for missile launches with little warning.
