It comes as United States president Donald Trump has warned North Korea it should be "very, very nervous" of the consequences if it considers attacking US soil.

Mr Trump's latest threat follows North Korea announcing a detailed plan to send four missiles over Japan and towards the island of Guam, where 6,000 US soldiers are based.
