However, the terms of the September 2006 Ceasefire between the government and the last remaining armed opposition group, the FLN (Forces for National Liberation, also called NLF or FROLINA), were not totally implemented, and senior FLN members subsequently left the truce monitoring team, claiming that their security was threatened. In September 2007, rival FLN factions clashed in the capital, killing 20 fighters and causing residents to begin fleeing. Rebel raids were reported in other parts of the country. The rebel factions disagreed with the government over disarmament and the release of political prisoners. In late 2007 and early 2008, FLN combatants attacked government-protected camps where former combatants were living. The homes of rural residents were also pillaged.
