France's top court reinstates ban on comic Dieudonne
The highest court in France reinstated a ban on a show by controversial comic Dieudonne M'bala M'bala, just before it was due to open.
Interior Minister Manuel Valls appealed to the Council of State to intervene minutes after a judge in the city of Nantes overturned the ban.
The comic has seven convictions for anti-Semitic hate speech.
Shocked fans booed outside the concert hall in Nantes, where more than 5,000 people had been due to see the show.
On his Facebook page, Dieudonne appealed to those gathered outside Nantes' Zenith venue to return peacefully to their homes, saying he had been denied permission to address them.
He promised to post a new video on his YouTube channel.
The judge in Nantes had earlier said he did not regard the show, entitled The Wall, as having "an attack on human dignity as its main object".
But the Council of State upheld the ban on Thursday's performance, the first on a scheduled tour, despite a challenge by the comic's lawyers saying his freedom of expression had been breached.
The council cited the risk to public order in its reinstatement of the ban.
The president of the World Jewish Congress, Ronald Lauder, had called on France to "confront this preacher of hate head on".
The government can be satisfied that a man they regard as a dangerous anti-Semite has been kept from the public arena, the BBC's Hugh Schofield reports from Paris.
Dieudonne's supporters will say it is just more evidence of how he and his ideas are silenced by the system, he adds.
'Peddlers of hate'
Some of the fans outside the Zenith gave Dieudonne's trademark quenelle gesture, which is regarded by many as an inverted Nazi salute.
Some fans brandished pineapples. One of the comic's most notorious songs, Shoananas, roughly translates as Pineapple-Holocaust and mocks commemoration of the Nazi extermination of the Jews.
French media who have sent reporters to previous performances of The Wall say it contained a string of derogatory references to Jews.
Speaking on Thursday from Brittany, Mr Valls said that "peddlers of hate stop at nothing and show boundless creativity".
"Faced with this creativity of hate, should we do nothing? Certainly not. The status quo is not a solution," he said.
The French government made a concerted effort to stop the tour after Dieudonne was recorded making remarks about Jewish journalist Patrick Cohen.
"When I hear him talking, I say to myself: Patrick Cohen, hmm... the gas chambers… what a shame," Dieudonne was recorded as saying.
He has also been accused of deriding Holocaust survivors and victims in his material.
On Monday, Mr Valls said he had advised city mayors and police prefects that Dieudonne's show could be banned if it was deemed to present a threat to public order.
However, Dieudonne's lawyer said banning the show would be a clear breach of the principle of free expression, and that contrary to government claims, there was no evidence that his performances were a threat to public order.
Dieudonne remains booked to play at a series of French venues until June, although the cities of Bordeaux and Marseille have cancelled his performances and in light of the latest ruling, it is not clear whether the rest of the tour can go ahead.
He describes the quenelle as an anti-establishment sign, not a Nazi salute.
It made headlines in the UK in late December when used by West Bromwich Albion footballer Nicolas Anelka during a goal celebration.
The striker said the gesture had been "a dedication to Dieudonne", not an anti-Semitic salute.
