North Korea test launches ICBM as South Korea and Japan leaders set to meet

South Korean president Yoon Suk Yeol says North will pay a price for launch on eve of Tokyo summit

North Korea has test-launched an intercontinental ballistic missile (ICBM) in a display of military might, just hours before the leaders of South Korea and Japan were to meet at a Tokyo summit that was expected to be overshadowed by Kim Jong-un's nuclear threats.

The launch on Thursday, the North's first ICBM test in a month and third weapons test this week, also comes as South Korean and US troops continue joint military exercises that Pyongyang sees as a rehearsal to invade.
