North Korean state media says an intercontinental ballistic missile was launched over the Sea of Japan on Saturday to test its reliability – its 3rd test of the long-range weapon in less than a year. The missile flew about 900km east for 67 minutes before landing in the ocean. Analysts say Pyongyang is retaliating against joint exercises planned by the US and South Korea next month with “enemy” drills. North Korean leader Kim Jong Un’s sister Kim Yo-jong has warned the hostile acts would be met with an “overwhelming” response. Japanese authorities said the missile could have travelled further – about 13,000km further – meaning it could reach the US mainland. Leaders meeting at the Munich Security Conference condemned North Korea’s actions, saying they “threaten regional and international peace and security”.
