Difficulties remain in Haitian aid relief

Aid workers are still facing big challenges to get relief supplies to Haitians left homeless by the earthquake. The UN says more food, water and medicines are urgently needed.

People are queueing for food handouts. It's now a common sight in Haiti. The UN World Food Program says about two million Haitians will need regular food aid until December. Seventy-five trucks are coming from the Dominican Republic to help distribute food to a wider area. But a US official says the level of the disaster makes things especially difficult.

Lewis Locke, US Special Coordinator in Haiti, said, "It happened here in a concentrated urban area where there is an immense number of people and the transportation is restricted, the inflow of commodities even if it were perfect there are going to be bottlenecks. In no way is that an excuse."
