North Korea releases jailed US student Otto Warmbier said to be in a coma

Mr Warmbier was sentenced last year to 15 years in jail for trying to steal a propaganda sign from a hotel.

Mr Tillerson said in a statement said: “At the direction of Donald Trump, the Department of State has secured the release of Otto Warmbier from North Korea”.

Mr Warmbier, a student from the University of Virgina, went with his tour group to North Korea in January 2016.
