A photo of late caricaturist Cabu is placed on bouquets of flowers as people pay tribute tribute to the shooting victims in front of the offices of the weekly satirical newspaper Charlie Hebdo in Paris January 10, 2015. French police searched for a female accomplice to militant Islamists behind deadly attacks on the satirical Charlie Hebdo weekly newspaper and a kosher supermarket and maintained a top-level anti-terrorist alert ahead of a Paris gathering with European leaders and demonstration set for Sunday. In the worst assault on France's homeland security for decades, 17 victims lost their lives in three days of violence that began with an attack on the Charlie Hebdo weekly on Wednesday and ended with Friday's dual hostage-taking at a print works outside Paris and kosher supermarket in the city.
