Cholera-struck Haiti set for presidential election
Haiti is preparing for its presidential election on Sunday, despite calls from some candidates to postpone the vote.
More than a million people are still homeless following the devastating earthquake that hit the country in January, and the UN has issued a new appeal for help to deal with the cholera epidemic.
One of most popular candidates, the former president Jean-Bertrand Aristide, has been barred from standing on a technicality.
