Pope Francis was admitted to a Rome hospital on Sunday afternoon for “scheduled surgery” on his colon later in the day, the Vatican said.

Francis is sometimes short of breath because a part of one of his lungs was removed following an illness when he was a young man in his native Argentina.

In 2014, a year after he was elected pope, Francis was forced to cancel several engagements because of what was believed to be a stomach ailment.
