North Korea says it tested "most powerful" weapon to date

North Korea says it tested a new solid-fuel intercontinental ballistic missile - its "most powerful" missile to date.

The state's Korean Central News Agency hailed Thursday's launch - which triggered a brief evacuation order in Japan - a "miraculous success".

Solid-fuel missiles can be fired more quickly than liquid-fuel ones, making them harder to detect and intercept.

The test would make rivals "suffer from extreme fear and anxiety", North Korean leader Kim Jong Un reportedly said.

South Korea on Friday said the technology displayed was not new and the North would need more time and effort to develop a fully functional solid-fuel ICBM.
