Adelaide Mukantabana (C), 52, a survivor of the 1994 Rwandan genocide prepares to throw flowers in the Garonne river in Bordeaux, western France, on April 7, 2014, as she takes part in the celebration of the 20th anniversary of Rwanda's genocide. Solemn commemorations marking the 20th anniversary of Rwanda's genocide on April 7 bore reminders of a festering anger as a major diplomatic row broke out over allegations of France's complicity in the 1994 massacres. Official mourning, which began three months ago with a flame of remembrance touring towns and villages across the small central African nation, culminates on April 7 when the torch arrives at the national genocide memorial.
