Aid organizations said Sunday they feared the nutritional crisis could deepen in impoverished Haiti, where skyrocketing food prices have already led to deadly protests and the ouster of the nation's No. 2 politician. With anger over food prices threatening the stability of this Caribbean nation already haunted by chronic hunger, the UN World Food Program appealed for donations to meet its US$96 million (â‚¬61 million) aid goal for Haiti. It has collected less than 15 percent of the annual budget goal. On Saturday, President Rene Preval announced subsidies to lower the price of rice and Haitian lawmakers fired Prime Minister Jacques Edouard Alexis for failing to boost food production. But aid workers said the measures might not be enough to ease popular anger if hunger continues to rise.
