North Korea's 'Hwasong-15 missile': Intercontinental ballistic missile (ICBM) that can reach London and Washington D.C

The new long range missile launched by North Korea early on Wednesday can reach targets at a distance of more than 8,000 miles, putting Britain and anywhere in the continental United States well within range of Kim Jong-un. Called the  Hwasong-15, the missile was launched at 3:17am local time from a site to the north of Pyongyang, flying for 53 minutes before falling into the Sea of Japan, within Japan's exclusive economic zone.
While Washington and Tokyo initially stated that they believed the weapon to have been one of the regime's Hwasong-14 missiles, North Korea announced hours later that it had tested a new intercontinental ballistic missile (ICBM). It landed in Japanese waters but flew higher than any other missile the North had previously tested.
South Korea responded by carrying out live-fire exercises, launching one of its own ballistic missiles. 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.
North Korea has previously said that its projectiles can hit the US but this marks the first time it says it can do it with this new type of missile, which appears to be an upgraded version of previous models. KCNA added that North Korean leader Kim Jong-un, who personally signed off on the launch, "declared with pride that now we have finally realised the great historic cause of completing the state nuclear force, the cause of building a rocket power".
