Turin Shroud on Italian television
The Turin Shroud, revered by many Christians as the burial cloth of Jesus, has been shown on Italian television in a special programme.
Pope Francis contributed a video message to the programme, in which he was careful not to authenticate the cloth, instead calling it an "icon" that "speaks to our hearts".
The BBC's David Willey says an Italian media company has also created a smartphone app showing detailed images of the fragile piece of material which are invisible to the naked eye.
