North Korea has cancelled today's high-level talks with South Korea because of anger over its joint military exercises with the US. It also warned the US over the fate of the historic summit between Kim Jong-un and US President Donald Trump that is scheduled for 12 June in Singapore.

"We will both try to make it a very special moment for World Peace!" the US leader later tweeted. The US state department said it was continuing to prepare for the Trump-Kim summit and that it was not aware of any changes in the North Korean position. The latest drills - known as Max Thunder - involve some 100 warplanes, including an unspecified number of B-52 bombers and F-15K jets. The North has described them as a "provocation" and preparation for a future invasion.North Korea fired a warning shot at the US when it announced it was cancelling Wednesday's talks with the South.
