President Trump has denied paying North Korea money for the medical care of comatose US student Otto Warmbier.

Warmbier was jailed in North Korea in 2015 during an organised tour and died after being returned to the US in a coma after 17 months in detention.
Earlier reports said that the US had been billed $2m (£1.5m) for the student's medical care.
North Korea had allegedly demanded the bill be paid before he was allowed to return home.
Mr Trump denied the claim on Twitter on Friday. He wrote: "No money was paid to North Korea for Otto Warmbier, not two Million Dollars, not anything else."
