The bus was empty at the time of the incident but was being used to transport Juventus fans to the game in Turin, the ANSA news agency reported.

The incident occurred at a service area outside Turin on the A21 highway, ANSA reported, adding that the fan was 28 years old. The incident reportedly followed scuffles between fans, and the bus driver was moving the vehicle around when the incident occurred.

Both teams announced the postponement of the game on their websites.

'Juventus and Parma, with the approval of the appropriate authorities, have decided to postpone the game as a sign of mourning for the incident involving the Parma fan that was traveling to the Turin stadium,' the statement said.

'Since it was a tragic fatality, the two clubs decided that the conditions were not right to send the teams out on the field.' In November, a Lazio fan was killed by police at a highway rest stop, sparking riots throughout the country. -- AP
