ROME -- Pope Francis was resting Monday morning after a quiet night, on the 10th day of his hospitalization for a complex lung infection that has provoked the early stages of kidney failure, the Vatican said. The one-line statement didn’t say if Francis, 88, had woken up. “The night passed well, the pope slept and is resting,” it said.

The Vatican described his condition as critical for the first time on Saturday, reporting that the 88-year-old Francis needed supplemental oxygen and blood transfusions after a "prolonged asthma-like respiratory crisis.

The Holy See has announced that blood tests showed early signs of kidney failure in Pope Francis, who has been in hospital battling a complex lung infection for over a week.
