Burkina Faso's interim President Michel Kafando has been freed and is in good health, the new junta leaders say.
However,
Prime Minister Isaac Zida, who was also detained when the presidential
guard stormed a cabinet meeting on Wednesday, remains under house
arrest.The coup leaders have agreed to the "principle of dialogue", as two West African leaders arrive to mediate.
The US, France and the African Union (AU) have condemned the takeover in the former French colony.
At least three people have died in protests in the capital, Ouagadougou, after an ally of ex-President Blaise Compaore was named leader on Thursday.
The influential Balai Citoyen civil society group has put the number of people who have died in demonstrations against the presidential guard (RSP) , at 10.
An unknown number of protesters have also been detained.
This will include Senegal's President Macky Sall, the current Ecowas chair, and Benin's leader Thomas Boni Yayi.
According to the Reuters news agency, security forces again fired in the air on Friday to disperse to demonstrators who burned tyres and blocked streets in the city.
Elections were due to be held in the West African nation on 11 October, nearly a year after a popular uprising forced Mr Compaore, the long-time ruler of the West African country, from power.
Coup leader Gen Gilbert Diendere, who was Mr Compaore's former chief-of-staff, told reporters that Mr Kafando was now in his official residence, after being freed on Thursday.
However, Mr Kafando has not yet been seen in public.
Two other minister have also been released, the coup leaders say.
The decision to free them was made "as a sign of easing tensions and in the general interest", a statement read on national television said.
Prime Minister Zida was the army officer who took charge after Mr Compaore was ousted.
The
lieutenant colonel was number two in the RSP, where he may still hold
influence, which explains his continued detention, says BBC Afrique's
Lamine Konkobo.
