Police officers stand outside the parliament in Tunis March 18, 2015. Gunmen in military uniforms stormed Tunisia's national museum, killing 17 foreign tourists and two Tunisians on Wednesday in one of the worst militant attacks in a country that has largely escaped the region's "Arab Spring" turmoil.
