Marseille mourns one of its own during a silent march for Medhi Kessaci

It was a murder that shocked France and alarmed the government. Mehdi Kessaci, the younger brother of anti-drug activist Amine Kessaci, was shot and killed in broad daylight on November 13th in what authorities believed was a warning to silence Amine. Thousands joined a silent march in Marseille to pay tribute to the slain 20-year-old.
