The family of a US student who died shortly after being freed from North Korea have declined a post-mortem examination, according to a US coroner. Otto Warmbier died on Monday near his family home in Ohio after more than 15 months in North Korean captivity. The Hamilton County coroner said only an external exam was performed on Mr Warmbier, who arrived home in a coma. North Korea claims his coma was due to botulism and a sleeping pill, but the Warmbier family and doctors disagree.
