The Vatican says Pope Francis is resting after a quiet night. Monday is the 10th day of his hospitalization for a complex lung infection that has provoked the early stages of kidney failure.

Pope Francis remains in critical condition, according to the Vatican, with blood tests showing mild signs of kidney failure “which is currently under control,” the Vatican said Sunday.

The press office for the Vatican said Sunday that Pope Francis was able to rest overnight as he slowly recovers from double pneumonia after initially being hospitalized for bronchitis.
