Haitian Prime Minister Jacques Edouard Alexis was voted out of office by the country's senate today after violent protests over rising food prices, news agencies reported. President Rene Preval, who called the no-confidence vote ``unjust,'' announced a 15 percent cut in the price of rice, which had doubled this week to $70 for a 50-kilogram (110-pound) bag, Agence France-Presse reported. No replacement for Alexis was announced. Haiti is the latest country to suffer unrest from soaring costs for basic foods, joining a list that includes Egypt, Mexico and Ivory Coast. Dominique Strauss-Kahn, the director of the International Monetary Fund, said today that rising prices for wheat, corn and soybeans could wipe out a decade of progress in the developing world.
