PORT-AU-PRINCE, Haiti (AP)- Frustrated presidential candidates led a march through Haiti’s capital Thursday to demand officials annul an election they say was tainted by fraud.

At least four of 19 candidates on Sunday’s ballot walked with hundreds of supporters to an electoral council office. They denounced electoral officials, President Rene Preval and the ruling Unity party’s candidate, state construction company chief Jude Celestin, chanting: “Prison for Preval, liberty for Haiti!”

“These were not elections. People were not allowed to vote and there was stuffing of the election boxes … We need democratic elections,” candidate Charles Henri-Baker, a factory owner, told The Associated Press.

The presidential hopefuls were part of a group of 12 candidates who called for voting to be canceled while polls were open, alleging the election was rigged in favor of Celestin.
