Accord, called for Libya to withdraw its troops, and promised to provide a peacekeeping unit, the Inter-African Force (IAF). Goukouni was skeptical of OAU promises, but in September he received a French pledge of support for his government and the IAF. But as Goukouni's relations with the OAU and France improved, his ties with Libya deteriorated. One reason for this deterioration was that the economic assistance that Libya had promised never materialized. Another, and perhaps more significant, factor was that Gaddafi was strongly suspected of helping Goukouni's rival within GUNT, Acyl Ahmat, leader of the Democratic Revolutionary Council (Conseil Démocratique Révolutionnaire or CDR). Both Habré and Goukouni feared Acyl because he and many of the members of the CDR were Arabs of the Awlad Sulayman tribe. About 150 years earlier, this group had migrated from Libya to Chad and thus represented the historical and cultural basis of Libyan claims in Chad. Habré overthrows Goukouni As a consequence of the Libya-Chad rift, Goukouni asked the Libyan forces in late October 1981 to leave, and by mid-November they had complied. Their departure, however, allowed Habré's FAN - reconstituted in eastern Chad with Egyptian, Sudanese, and, reportedly, significant United States assistance - to win key positions along the highway from Abéché to N'Djamena. Habré was restrained only by the arrival and deployment in December 1981 of some 4,800 IAF troops from Nigeria, Senegal, and Zaire. In February 1982, a special OAU meeting in Nairobi resulted in a plan that called for a ceasefire, negotiations among all parties, elections, and the departure of the IAF; all terms were to be carried out within six months. Habré accepted the plan, but Goukouni rejected it, asserting that Habré had lost any claim to legitimacy when he broke with GUNT. When Habré renewed his military advance toward N'Djamena, the IAF remained essentially neutral, just as the French had done when the FROLINAT marched on Malloum three years earlier. FAN secured control of the capital on June 7. Goukouni and other members of GUNT fled to Cameroon and eventually reappeared in Libya. For the remainder of the year, Habré consolidated his power in much of war-weary Chad and worked to secure international recognition for his government.
