Fans of Swiss club Basel are banned from travelling to Nice on Thursday for the quarter-final second leg of the Europa League Conference. The Ministry of the Interior justifies its decision by the fact that FC-Basel's movements are "frequently a source of disturbance to public order" Violent clashes also took place between Nice fans and those of the German club FC Cologne in September 2022, in the stands of the Allianz Riviera.

In these incidents, 32 people were injured, one seriously, and four were hospitalized.
