Pope Francis is resting Thursday after a peaceful night during his third week of hospital treatment for double pneumonia.

Pope Francis, who has been in hospital for almost three weeks battling double pneumonia, has spent another "tranquil" night and is still resting, the Vatican said on Thursday. The 88-year-old pontiff was admitted to Rome's Gemelli hospital on February 14 with a severe respiratory infection that has required continuously evolving treatment.

Pope Francis, who has been struggling to overcome double pneumonia for almost three weeks, remained in stable condition throughout the day on Wednesday and has not had any new breathing crises, the Vatican said.
