"We organise a silent, solidarity-based, humanist and peaceful march, which will open with a single long white banner. No political demands, no slogans. White flags and white handkerchiefs are welcome", wrote a press release from a group called "Another Voice", chaired by the Belgian actress Lubna Azabal.
The march started at the Institut du Monde Arabe and proceeded to the Musée d'Art et d'Histoire du Judaïsme, ending at the Arts et Métiers metro station.
The signatories included actors and actresses such as Sami Bouajila, Pierre Richard, Elsa Zylberstein and Laure Calamy, author Leïla Slimani, cartoonist Philippe Geluck and singer Michel Jonasz.
