was a province of the Ottoman Empire for much of its history. AIS unilateral truce The AIS, which at this point was engaged in an all-out war with the GIA as well as the Government, found itself in an untenable position. The GIA seemed a more immediately pressing enemy, and AIS members expressed fears that the massacres—which it had condemned more than once—would be blamed on them. On 21 September 1997, the AIS' head, Madani Mezrag, ordered a unilateral and unconditional ceasefire starting 1 October, in order to "unveil the enemy that hides behind these abominable massacres." The AIS thus largely took itself out of the political equation, reducing the fighting to a struggle between the Government, the GIA, and the various splinter groups that were increasingly breaking away from the GIA. Ali Benhadjar's FIS-loyalist Islamic League for Da'wa and Jihad (LIDD), formed in February 1997, allied itself with the AIS and observed the same ceasefire. Over the next three years, the AIS would gradually negotiate an amnesty for its members. GIA destroyed, 1998–2000 After receiving much international pressure to act, the EU sent two delegations, one of them led by Mário Soares, to visit Algeria and investigate the massacres in the first half of 1998; their reports condemned the Islamist armed groups. The GIA's policy of massacring civilians had already caused a split among its commanders, with some rejecting the policy; on 14 September 1998, this disagreement was formalized with the formation of the Salafist Group for Preaching and Combat (GSPC), based in the mountains west of Kabylie and led by Hassan Hattab. Massacres continued throughout 1998 attributed to "armed groups that had formerly belonged to the GIA", some engaged in banditry, other settling scores with the patriots or others, some enlisting in the services of landowners to frighten illegal occupants away. Eventually towns soon became safer, although massacres continued in rural areas. On 11 September, President Zéroual surprised observers by announcing his resignation. New elections were arranged, and on 15 April 1999, the army-backed ex-independence-fighter Abdelaziz Bouteflika was elected president with, according to the authorities, 74% of the votes. All the other candidates had withdrawn from the election shortly before, citing fraud concerns. Bouteflika continued negotiations with the AIS, and on 5 June the AIS agreed, in principle, to disband. Bouteflika followed up this success for the Government by pardoning a number of Islamist prisoners convicted of minor
