Arriving in Rome after Pope Francis's death, Catholic cardinals have admitted some apprehension at the responsibility of choosing his successor, as they begin setting out what they hope to see in the next head of the Church.
The task of choosing a new pope to replace the Argentine, who died on Monday aged 88, "is beyond us and yet requires us", said French cardinal Jean-Marc Aveline, summing up the mood after celebrating a mass on Thursday evening.
