Pope Francis "remained stationary" on Wednesday, "without showing any episodes of respiratory failure," but rested peacefully overnight into Thursday, the Vatican said.

Pope Francis, who has been in hospital for almost three weeks battling double pneumonia, is in stable condition and is doing some physical therapy, 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 had a good night in hospital in Rome, the Vatican said on Thursday morning, where he is being treated for pneumonia. "The night passed quietly; the pope is still resting," the Holy See Press Office said in a statement.
