Pope Francis, battling double pneumonia, remains in a critical condition and his prognosis is still guarded because of the "complexity" of his clinical condition, the Vatican said on Sunday.

ROME — Pope Francis was conscious but still receiving high flows of supplemental oxygen Sunday following a respiratory crisis and blood transfusions, as he remains in critical condition with a complex lung infection, the Vatican said.

Pope Francis, who has been hospitalized for more than a week, remains in “critical” condition and developed an “asthmatic respiratory crisis” earlier on Saturday, the Vatican said in a statement.
