Many bombings were committed during the Algerian Civil War that began in 1991. The Salafist Group for Preaching and Combat (GSPC) claimed responsibility for many of them, while for others no group has claimed responsibility. These terrorist incidents generated a widespread sense of fear in Algeria. The number of bombings peaked in 2007, with a smaller peak in 2002, and they were particularly concentrated in the areas between Algiers and Tizi Ouzou, with very few occurring in the east or in the Sahara. This list is not exhaustive and sources frequently disagree on the number of deaths.
