Mark is back in Toronto as we continue to bring you the latest on the earthquake in Haiti.

Tonight we hear from a photographer at one of the mass graves, and a doctor in Haiti who can explain what the greatest needs are right now. We take a look at the challenges of delivering aid, as well as the security situation in the country. Also, the politics and history of the first black republic to declare independence.
