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.

The Vatican said Pope Francis has the "onset of bilateral pneumonia," and that tests, a chest X-ray and the pope's clinical condition present a "complex picture."
