Pope Francis said on Sunday the mistreatment of migrants escaping war and injustice "makes one cry" as he visited the northern Italian city of Turin, stopping to pray before an icon some Christians believe is Jesus' burial cloth.
The Church has not taken an official position, saying the mysterious cloth that has baffled scientists is at least a powerful reminder of Jesus' suffering.
Francis was the latest in a string of popes to pray before the shroud, which is usually kept locked out of sight behind an altar, and is on display for only the third time in 17 years. Hundreds of thousands of people have seen it since the current display began in April.
