The pontiff's condition is touch-and-go, given his age, fragility and pre-existing lung disease, according to doctors.

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.

Officials said Pope Francis is in critical condition as he battles pneumonia and early kidney failure. He was awake and eating normally during his treatments. Crowds have been gathering at Vatican City to pray for his recovery. Doctors reported Sunday that blood tests showed his early kidney failure was under control.
