In Haiti, hundreds have marched in the capital Port-au-Prince calling on the United Nations to pay reparations for the cholera epidemic that’s killed more than 6,000 people. Some 450,000 Haitians have also been sickened since the cholera outbreak erupted in October 2010. This week, former President Bill Clinton, the U.N. special envoy to Haiti, acknowledged that the outbreak likely originated with a battalion of Nepalese troops with the U.N. peacekeeping mission.
