Italian police kill football fan
The victim was shot near a motorway restaurant in Tuscany
A football fan has been shot dead by police during a fight between rival supporters in Italy, officials say.
Local authorities said there had been a "tragic error" when police intervened to quell violence between fans of Roman team Lazio and Turin-based Juventus.
The victim, a Lazio fan, was shot during the clash at a motorway rest stop near the Tuscan city of Arezzo.
The Lazio fans were travelling to a match against Inter Milan, which has been suspended following the death.
Other games were starting 10 minutes late with players and officials wearing black armbands.
The Juventus fans were reportedly on their way from Naples to an away match against Parma.
"It was a tragic error," said Arezzo police chief Vincenzo Giacobbe.
"Our agent had intervened to prevent the brawl between these two groups, who had not been identified as fans," Mr Giacobbe said, according to the Italian news agency Ansa.
The victim was identified as Gabriele Sandri, a 26-year-old disc jockey from Rome.
He was apparently shot while in a car outside the motorway restaurant.
Earlier reports said the fan had been killed during the brawl. An investigation is under way.
News of the violence sparked clashes between fans and police in Bergamo, where Atalanta were playing AC Milan.
That match was abandoned 10 minutes after kick-off, when fans tried to smash down a barrier and force their way onto the pitch.
In April the Italian government introduced a law aimed at stamping out football hooliganism.
It was enacted after a policeman was killed in rioting at a match in Sicily in February.
