A protester holds a placard which reads "I am Charlie" as she takes part with hundreds of thousands of French citizens in a solidarity march (Marche Republicaine) in the streets of Paris January 11, 2015. French citizens were 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, including journalists and policemen, 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.
