The opposition group - National Front for the Defence of the Constitution (FNDC) - wants clarity on who is part of the junta and the duration of the transition to civilian rule.

Col Mamady Doumbouya seized power in September, deposing Alpha Condé as president.

A recently leaked document suggested there would be a four-year transition, but the authorities have not commented on it.

The opposition group compared this to the situation to Burkina Faso where soldiers took power in January.

The Burkinabè junta set up a committee quickly and a timetable of the transition has been made public.
