North Korea has claimed that the missile it tested on Sunday was a new type of rocket capable of carrying a large nuclear warhead.

The missile, launched at a steep angle, reached an altitude of 2,000km (1,242 miles) and travelled about 700km, landing in the sea west of Japan.

North Korea said on Monday it was a test of the abilities of a "newly developed ballistic rocket".
