The African Union (AU) has given Burkina Faso’s military a two-week deadline to hand power to a civilian ruler or face sanctions.
The AU said the army had acted unconstitutionally when it took over after President Blaise Compaore was forced to resign last Friday.
The military said a civilian-led transitional government would be established as quickly as possible.
Mr Compaore quit after mass protests at his bid to extend his 27-year rule.
On Saturday, the military named Lt Col Isaac Zida, previously second in command of the presidential guard, as the new interim ruler.
