Pope Francis experienced more respiratory problems and went on noninvasive ventilation on Monday, the Vatican said, as the head of the Roman Catholic Church battles double pneumonia in the hospital.

Doctors not involved in his care said Pope Francis likely has a mix of bacteria, viruses, fungi and parasites in his lungs. Experts said it should be treatable with antibiotics, but it's unclear how long that might take.

The Vatican says Pope Francis has emerged after a three-hour abdominal surgery with no complications. He was admitted for a procedure to open up his abdomen after developing a hernia linked to a 2021 operation.
