Pope Francis had a restful 10th night in the hospital, according to a statement published this morning by the Holy See Press Office.

"The night went well, the Pope slept and is resting," read the statement.

The Pope is receiving treatment for double pneumonia at the Gemelli Hospital in Rome.

On Sunday evening, the Holy See Press Office said his condition remains critical, though he has not experienced any respiratory crises since Saturday morning.

Pope Francis had received blood transfusions to bring up his haemoglobin levels.
