The AIS, faced with attacks from both sides and wanting to dissociate itself from the GIA's civilian massacres, declared a unilateral ceasefire on 21 September 1997 (in order to "unveil the enemy who hides behind these abominable massacres"), and disbanded in 1999. Thousands of AIS fighters surrendered and handed over their weapons to the authorities. In January 2000 those fighters obtained amnesty under the terms of the "Civil Concord" decreed by President Abdelaziz Bouteflika after his election in April 1999. Both Mezrag and Benaïcha offered their services to the authorities to fight the GIA and the Salafist Group for Preaching and Combat (GSPC), which has links to Al-Qaeda.
