New satellite photos show North Korea's nuclear weapons programme is growing quickly and could soon be able to hit Alaska and Hawaii

New satellite photos have emerged that suggest North Korea's nuclear programme is growing more quickly than first believed.

Experts claim the images show a test site in the Asian country that could soon be capable of launching a missile that could hit Alaska or Hawaii.

Satellite image firm Planet has provided the photos and say scorch marks in the ground are evidence Kim Jong-un may be testing the Hwasong-12 rocket, which is able to travel 2,500 miles, North Korea claims.

It would mean targets in Guam, Alaska and Hawaii would be within range of a nuclear attack.
