Funeral for North Korea captive Otto Warmbier held in Ohio

Otto Warmbier, who died only days after his return to the US following more than 15 months of captivity in North Korea, was laid to rest in his Ohio hometown on Wednesday.

Warmbier's roommate in North Korea tells the BBC about how "surreal" and "upsetting" his arrest and illness have been.
