Pope Francis rested overnight in the hospital, the Vatican said earlier Sunday, adding that his night "passed peacefully."

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.

Pope Francis appears to have an "early, mild renal insufficiency" as he remains hospitalized in critical condition, the Holy See Press Office said in Sunday evening update.
