Haiti is the poorest nation in the Western Hemisphere and, in the last 15 years, the Caribbean nation has had outbreaks of cholera, a devastating earthquake and continual political upheaval. Last year, its president was assassinated - a crime for which no one has yet been put on trial, and since then violence in Haiti has escalated. According to human rights groups, armed gangs now control at least 60% of the capital, Port au Prince. In October, the UN reported 200 killings and 100 kidnappings. Host James Reynolds hears from Haitians who are dealing with the threats and dangers affecting them.
