Pope Francis was in critical condition Saturday after he suffered a long asthmatic respiratory crisis that required high flows of oxygen, the Vatican said.

The 88-year-old Francis has pneumonia in both lungs and remains in critical condition despite showing a slight improvement after 11 days in the hospital.

ROME (AP) — Pope Francis remained in critical condition Monday but showed slight improvement in laboratory tests and resumed some work, the Vatican said, including calling a parish in Gaza City that he has kept in touch with since the war there began.
