VATICAN CITY >> Pope Francis’ health has deteriorated over the past 24 hours, the Vatican said in a statement today, adding that he had suffered a “prolonged asthma-like respiratory crisis” and had needed blood transfusions.

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.
