French citizens will be joined by dozens of foreign leaders, among them Arab and Muslim representatives, in a march on Sunday in an unprecedented tribute to this week’s victims following the shootings by gunmen at the offices of the satirical weekly newspaper Charlie Hebdo, the killing of a police woman in Montrouge, and the hostage taking at a kosher supermarket at the Porte de Vincennes.
