An emerging movement of believers known as Salafis has seemingly appeared out of thin air _ and prompted fears of a culture war in this North African country of 10 million. Since the overthrow of President Zine El Abidine Ben Ali in January 2011 unleashed a string of Arab uprisings, Islam has blossomed in Tunisia in a way it wasn't allowed to do for half a century.(AP Photo/Amine Landoulsi, File)
