North Korea's Latest Missile Launch Causes Alarm in Japan and South Korea.

North Korea launched a new type of ballistic missile, possibly using solid fuel, which may be more mobile and harder to detect, according to South Korea's military. The missile was launched on a high angle from near Pyongyang and fell in the waters between the Korean Peninsula and Japan following a 620-mile flight. Japan briefly urged residents on a northern island to take shelter. North Korea's known ICBMs all use liquid propellants that must be fueled before launches, but a solid-propellant weapon is already loaded, enabling it to be moved more easily and fired more quickly.
