• Otto Warmbier, the American college student who was returned from North Korea last week in a coma, has died, his family said in a statement.

It only emerged at his return that the 22-year-old had been comatose for more than a year. He had been sentenced in Pyongyang to 15 years of hard labor after being caught trying to steal a propaganda poster.

The family’s statement said he suffered “awful, torturous mistreatment” at the hand of North Koreans.
