North Korea claimed it has successfully tested a new type of intercontinental ballistic missile (ICBM) that can reach the whole of continental United States.

News of the launch was announced on state television in a special broadcast at midday, as well as in a report released by state news agency KCNA. State television said Pyongyang had achieved its mission of becoming a nuclear state.

The Hwasong-15 missile, described as its "most powerful", was launched in darkness early on Wednesday. It landed in Japanese waters but flew higher than any other missile the North had previously tested.

Pyongyang says the missile reached an altitude of 4,475km (2,780 miles) and flew 950km in 53 minutes, close to independent estimates made by South Korea's military.
