Burundi: Ex-rebel leader Agathon Rwasa quits elections

Five opposition candidates have withdrawn from presidential polls in Burundi due to take place on 28 June. They include the former rebel leader Agathon Rwasa, who was widely thought to be the key challenger to the current President Pierre Nkurunziza. All had called for the resignation of Burundi's electoral commission following local polls last month, which they say were fraudulent.
