A political and security crisis in Haiti continues after gunmen assassinated the country’s president, Jovenel Moïse, earlier this week. Now according to Haitian authorities, police have killed four suspects behind the assassination and arrested two others. But who was behind the killing — and why — remains unclear, along with who is actually leading Haiti now and down the road. Pamela White, who served as US ambassador to Haiti from 2012 to 2015, and is now with the School of Policy and International Affairs at the University of Maine, joins The World with the latest.
