Ahmed Ben Bella
After returning to Algeria, Khider joined Ahmed Ben Bella and the FLN army's chief of staff, Col. Houari Boumédiène, in forming a Political Bureau of the FLN to replace the GPRA, over which they had no control. Boumédiène's army, built up outside the war zone in Morocco and Tunisia, quashed resistance among GPRA loyalists and guerrilla units inside Algeria, as it moved in from its border area bases.
