North Korea's Kim Jong-un named marshal

North Korean leader Kim Jong-un has been given the title of marshal, state media has announced.

The move followed a high-level military reshuffle in which army chief Ri Yong-ho was removed ''due to illness'' and a little-known general promoted.

Lucy Williamson, reporting from Seoul, says Kim Jong-un is 'trying to consolidate his hands on the levers of military power'.
