US President Donald Trump has said there is a very substantial chance a historic summit with North Korea's Kim Jong‑un next month may not happen.
He said the North must meet conditions for the summit to go ahead though if it did not, it might happen later.
The North has said it may cancel the summit if the US insists on it giving up nuclear weapons unilaterally.
Trump did not say what conditions the US had set for the summit but when asked by a reporter about the North's arsenal, he said denuclearisation must take place.
The 12th June summit is due to take place in Singapore.
North Korea is expected to dismantle a nuclear test site this week as a good will gesture but the demolition may be delayed by bad weather.
