In this Wednesday, Sept. 12, 2012 photo, mourners from the Dawa sect gather for the burial of nine Mauritanian Muslim preachers killed last week in neighboring Mali, at a cemetery in the Riad neighborhood of Nouakchott, Mauritania. The nine were part of a group of 16 preachers who were traveling by truck from Mauritania to Mali for a religious conference. All 16 as well as their driver were gunned down by Malian soldiers at a checkpoint in the central Malian town of Diabaly. Early reports indicate that the long-bearded preachers were mistaken for the jihadists who took over Mali's north in April, imposing Shariah law and recently threatening to advance on Bamako, the Malian capital.
