 During the period between 1984 and 1986 , in which no major clash took place , Habré greatly strengthened his position thanks to western support and Libya 's failure to respect the Franco @-@ Libyan 1984 agreement . From 1984 onwards , the GUNT also suffered increasing factional tensions , centered on the fight between Goukouni and Acheikh ibn Oumar over the leadership of the organization . Taking advantage of the GUNT 's difficulties , Habré struck a series of accords with smaller rebel factions , which left the GUNT at the beginning of 1986 with only three of the eleven factions that had originally signed the Lagos Accord in 1979 . The remaining factions were Goukouni 's People 's Armed Forces ( FAP ) , Acheikh 's armed branch of the Democratic Revolutionary Council ( CDR ) and that part of the Chadian Armed Forces ( FAT ) which had maintained its loyalty to <unk> Abdelkader Kamougué .
