U.S. Secretary of State John Kerry has delayed his trip back to the United States to stay in a Swiss hospital overnight after breaking his leg in a bicycle crash Sunday.

That from State Department spokesman John Kirby, who said after further consultation that it was sensible for him to remain in the hospital for observation overnight for precautionary reasons.

Kerry had to scrap the rest of a four-nation trip that included an international conference on combating the Islamic State group.
