French authorities banned a far-right youth rally set for Saturday in the southern city of Toulouse after the killing of a left-wing student this week sparked alarm over street violence by ultra-right groups.
Toulouse's Socialist mayor had expressed concern about a planned torchlight evening march to commemorate the victory of a Christian army in 721 over Muslims besieging the city, after a clash between ultra-right and far-left youths in Paris on Wednesday led to the death of a 19-year-old student.
Toulouse police headquarters said it had feared a "serious risk of public disorder" if the rally went ahead.
