Tunisia declares nationwide curfew after violent job protests

Tunisia declared a nationwide curfew on Friday after four days of protests and rioting over jobs and economic conditions, the worst unrest since an uprising five years ago that toppled autocrat Zine El Abidine Ben Ali. There were further demonstrations on Friday in several regions, including Kasserine and Sidi Bouzid. Tunisia has been held up as a model for democratic progress since the 2011 revolution that toppled Ben Ali.
