“The Jews’ great concern,” reads the Thursday headline in French daily Aujourd’hui en France, above an image of a man wearing a skullcap. It comes after a teenager attacked and wounded a Jewish teacher who was wearing the traditional headgear Monday in Marseille, southern France.

France is debating whether it’s still safe for members of the Jewish community to wear the traditional accessory — also known as a kippah or yarmulke.

A 15-year-old boy claiming to act in the name of the ISIS assaulted the Jewish teacher with a machete, the third attack of its kind in Marseille in recent months.

Following the wave of violence, Zvi Ammar, head of Marseille’s Jewish Council, advised Jews to refrain from wearing their skullcaps, a recommendation that sparked controversy among the religious community.
