Donald Trump tells North Korea leader nuclear programme is 'putting you in grave danger'

President Donald Trump has delivered a sharp warning to North Korean leader Kim Jong Un, telling him the weapons he is acquiring "are not making you safer. They are putting your regime in grave danger."

In a speech delivered hours after he aborted a visit to the heavily fortified Korean demilitarised zone due to bad weather, Mr Trump called on all nations to join forces "to isolate the brutal regime of North Korea - to deny it any form of support, supply, or acceptance".
