Burkina Faso’s military ruler has told activist groups they have until Sunday afternoon to provide a list of candidates for interim national leader.
Lt Col Isaac Zida agreed a transition plan with civilian political groups on Thursday, but no leader was named.
The groups have agreed to submit a list of candidates to a 23-member council, which will then select a single leader.
Col Zida took over from long-time leader Blaise Compaore, who was ousted after mass street protests in October.
But then protests erupted against army rule after Col Zida suspended the constitution and cracked down on dissent.
International bodies threatened sanctions unless civilian rule was restored.
A deal was reached on Thursday to install an interim legislative chamber and a transitional leader until elections are organised next year.
In a communique on Saturday, Col Zida said civilian groups had until noon on Sunday to provide a list of candidates to serve as interim president.
He also said the constitution was back in force in order to “allow the start of the establishment of a civilian transition”.
