Faith factor in Haiti aid effort

Before the January 12 earthquake devastated Haiti, numerous faith-based humanitarian organisations operated in the predominantly Catholic island.

And now groups like the Church of Scientology International, Operation Blessing and the American Jewish World Service, have expanded their presence by sending in teams of volunteers, donating food, medicines and equipment.

However, some Haitians, including Haiti's head Voodoo priest, question the true motive behind these humanitarian acts.
