Troops loyal to Burkina Faso’s government massed in the capital on Tuesday and told soldiers behind a coup to disarm and surrender by 10 a.m. GMT (Kenyan Time) or face attack.
Rebel soldiers still controlled the presidential palace, but troops that oppose the coup held most other key points in Ouagadougou, witnesses said.
The situation remained fluid and loyalists said the rebelling soldiers had already started negotiations on the conditions of their surrender.
In one apparent olive branch, the coup leaders released interim prime minister Yacouba Isaac Zida, who had been held hostage since the revolt began, his adviser and another loyalist officer told Reuters.
Ex-spy chief General Gilbert Diendere and his presidential guard rebelled on Wednesday, raiding a cabinet meeting and detaining the president and other ministers.
