Crowds have been gathering at Vatican City to pray for his recovery. Doctors reported Sunday that blood tests showed his early kidney failure was under control.

Pope Francis remained in a critical condition Sunday and blood tests showed early kidney failure but he remains alert, responsive and attended Mass, the Vatican said, as the 88-year-old pontiff battles pneumonia and a complex lung infection.

Francis remains in critical condition but has not suffered any additional crises, the Vatican said Sunday evening, after reporting Saturday the pope suffered a “long asthmatic respiratory crisis” days after he was hospitalized for pneumonia.
