North Korea says it test-fired hypersonic missile

North Korea said Monday it had successfully test-fired a new ballistic missile tipped with a hypersonic manoeuvrable warhead, the latest breakthrough in its pursuit of advanced weaponry to threaten South Korean and US targets. The launch, Pyongyang's first known weapons test this year and its first ever test of a solid-fuel hypersonic intermediate-range ballistic missile (IRBM), was detected by Seoul's military Sunday afternoon. A short report in the official Korean Central News Agency said that the solid-fuel IRMB was "loaded with a hypersonic manoeuvrable controlled warhead".
