JOHANNESBURG - Officials have spent the day collecting bullet-riddled bodies from city streets in the Burundian capital of Bujumbura, after Friday's clashes in which nearly 90 people were killed in the country's worst outbreak of violence since a failed coup in May.

Unrest in Burundi, which started in April when President Pierre Nkurunziza announced plans for a third term in office, has unnerved a region still volatile two decades after the genocide in neighbouring Rwanda.

Friday's clashes were condemned by the United States, which like other western powers fears the central African nation could slide back into ethnic conflict.

Residents said some of Friday's dead were killed after being rounded up by the police in house-to-house searches, an allegation the police denied.
