The 88-year-old pontiff, who was admitted to the hospital last week, is being closely monitored by doctors as he undergoes treatment.

Pope Francis is "responding to therapy" for double pneumonia at a hospital in Rome but it not "not out of danger," the Vatican said Saturday.

Doctors on Friday said the 88-year-old Francis is "not out of danger" ​and that the main threat facing him would be the onset of sepsis.
