PORT-AU-PRINCE, Nov 20 (Reuters) - Canada has sanctioned former Haitian President Michel Martelly and two former prime ministers for financing gangs, Canadian authorities said on Sunday, the latest in a series of measures targeting alleged backers of Haitian criminal groups. In September, Haitian gangs created a humanitarian crisis by blocking a fuel terminal for nearly six weeks, halting most economic activity and triggering U.N. discussion of a possible foreign strike force to open the terminal. Canada and the United States have sanctioned political leaders who allegedly finance the gangs, which according to policy makers are backed by Haitian elites. Radio-Canada journalist Louis Blouin wrote on Twitter that the sanctions targeted Martelly, as well as former Haitian Prime Ministers Laurent Lamothe and Jean Henry Ceant. Ceant served as prime minister from 2018 to 2019.
