A crucifix is seen as a policeman stands next to the wreckage of a coach crash near the southern town of Avellino July 29, 2013. Thirty-nine people were killed and around 10 injured when the bus plunged off a viaduct in southern Italy in what Prime Minister Enrico Letta described on Monday as a huge tragedy.
