North Korea cancelled US meeting 'at last minute'

US vice president Mike Pence was all set to hold a history-making meeting with North Korean officials during the Winter Olympics in South Korea, but Kim Jong Un's government cancelled at the last minute, the Trump administration has said.

A potential meeting between Mr Pence and the North Koreans had been the most highly anticipated moment of the vice president's visit to Pyeongchang, South Korea, where he led the US delegation to the opening ceremonies.
