Pope Francis is "responding to therapy" for double pneumonia at a hospital in Rome but it not "not out of danger," the Vatican said Saturday.

LONDON — Vatican officials said late Tuesday that Pope Francis had developed pneumonia in both lungs, further complicating the pontiff’s recovery. The 88-year-old pope was hospitalized Friday after a weeklong bout of bronchitis worsened. On Monday, doctors said he had developed a mix of infections in his respiratory tract.

Pope Francis, who is being treated in hospital for double pneumonia, will not appear in public on Sunday to lead his usual prayer with pilgrims for a second consecutive week, the Vatican said. Francis is being treated at Rome's Gemelli hospital,
