Pope Francis has been in hospital for 11 days, with recent blood tests show early, mild kidney failure after he experienced a respiratory crisis. The 88-year-old pontiff is suffering from pneumonia in both his lungs.

Francis, 88, had remained in critical condition throughout the weekend after severe breathing difficulties were reported.

Pope Francis woke up and was continuing therapies Monday on the 10th day of his hospitalization for a complex lung infection that has caused kidney failure complications, the Vatican said.
