On Sunday, President Hollande announced that Huguette Dupeu, a Frenchwoman injured in the attack, had died from her wounds.As well as the French leader, Italian Prime Minister Matteo Renzi and other foreign dignitaries attended a ceremony at the museum where a stone tablet was dedicated to the memory of the attack victims.Speaking at the ceremony President Hollande pledged France's support."We had four French citizens killed there, victims of terrorism, so it was necessary to participate in this march," he said, adding: "Today it's about Tunisia, and the values it represents in the Arab world and beyond."Demonstrators waved Tunisian flags and held up slogans of "Not Afraid" and "We Are Bardo" as they marched, surrounded by a heavy security presence."We have shown we are a democratic people, Tunisians are moderate, and there is no room for terrorists here," demonstrator Kamel Saad told Reuters.Some leftist political groups chose to boycott the rally. They object to the participation of an Islamic party, who they hold accountable for the rise of Islamic extremism in the country.
