Commander Bertin Wafio of the Popular Army for Unity and Democracy in the Central African Republic has told Al Jazeera that his fighters will oppose the new unity government's plans for presidential elections next year.
That is unless more progress is made to disarm and reintegrate fighters following a peace deal agreed last year.
For 30 years, CAR went through a turbulent period, under the rule of mostly military governments.
The most infamous was the brutal decade-long rule by the self-proclaimed emperor, Jean-Bedel Bokassa.
In 1993, civilian rule was established and lasted for 10 years. Instability led to a military coup in March 2003.
