A lawyer's tweets justifying the October 7 attack embarrass the Lille bar. Eddine Denfer-Djeffal published numerous anonymous tweets legitimizing the attack.

He also propagated anti-Semitic clichés or ironicizing the Hyper Cacher attack. The Bar is taking "all necessary measures regarding the circumstances of these tweets and their consequences” - Me Florent Méreau, President of Lille Bar. He is a collaborator of the Masson-Dutat firm Lille, the two partners of the former presidents Emmanuel Masson and Marie-Christine Dutat.
