North Korean state TV has shown video of what it says was this week’s test of a new ballistic missile, which flew higher and for longer than any previous test.
The official Korean Central News Agency hailed it as "the world's strongest strategic missile" and leader Kim "expressed great satisfaction" at the successful launch.
The color and shape of the exhaust flames seen in North Korean media photos of the launch suggest the missile uses preloaded solid fuel, which makes weapons more agile and harder to detect than liquid propellants that in general must be fueled beforehand.
This means North Korea's new weapon can reportedly hit the US if fired.
