Nidaa Tounes

Tunisia’s president declared a 30-day state of emergency across the country and imposed an overnight curfew for the capital after an explosion Tuesday struck a bus carrying members of the presidential guard, killing at least 12 people and wounding 20 others.

Tunisia will hold its first presidential elections on Sunday, Nov. 23. Main candidates include former Interim Prime Minister Beji Caid Essebsi of the Nidaa Tounes Party, Moncef Marzouki of the Congress for the Republic (CPR), and Mustapha Kamel Nabli, a former governor of the Central Bank of Tunisia.

Campaign posters and banners for next week’s presidential elections have covered the walls of Tunisia’s cities and towns, papering over the flaking posters from the parliamentary elections just three weeks ago.
