PORT-AU-PRINCE, Safar 29, 1436, Dec 21, 2014, SPA -- Haitian Health Minister Florence Duperval Guillaume was named interim prime minister on Sunday to replace Laurent Lamothe, who resigned a week ago following several weeks of protests, Reuters reported. The announcement is part of an effort to resolve a mounting political crisis over long-delayed elections. Lamothe's resignation also came after international warnings from the United States and the United Nations that the impoverished Caribbean nation was on the brink of political chaos again. -- SPA 19:48 LOCAL TIME 16:48 GMT www.spa.gov.sa/w
