Burundi’s President Pierre Nkurunziza has said he will release 2,000 prisoners detained since protests broke out against his rule in April.
He made the announcement following talks with UN chief Ban Ki-moon in Burundi’s capital, Bujumbura.
About 400 people have been killed and 250,000 have fled to neighbouring states since Mr Nkurunziza announced in April that he would seek a third term.
He survived a coup attempt in May, and won elections in July.
Mr Ban’s visit was the latest in a series of diplomatic initiatives aimed at ending the unrest.
