French author Marek Halter (L) looks at an employee cleaning the word 'quenelle' written on "The Wall For Peace" at the Champs de Mars in Paris January 6, 2014. The expression "la quenelle" literally translates into English as meaning an elongated creamed fish dumpling but is also a reference to the French comedian Dieudonne's trademark straight-arm salute. France is considering banning performances by Dieudonne M'bala M'bala whose shows have, according to Interior Minister Manuel Valls last December, repeatedly insulted the memory of Holocaust victims and could threaten public order.
