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.

Pope Francis was in good spirits, was not in pain and was not receiving artificial nutrition, the Vatican said. The work he was doing included reading and signing documents, and indeed the Vatican's daily noon bulletin has included new bishop nominations nearly every day,
