The United States has imposed sanctions on former Haitian President Michel Martelly for drug trafficking and money laundering. A U.S. official said the sanctions against Martelly underscored the “destabilizing role he and other corrupt political elites have played in perpetuating the ongoing crisis in Haiti.” Martelly was Haiti’s president from 2011 to 2016.

This comes as the U.N.-backed, Kenyan-led police force deployed to Haiti almost two months ago appears to have made little inroads in addressing the spiraling insecurity and gang activity in the country.
