Several hundred thousand people are in need of food and water in Haiti, after tropical storm Hanna dumped massive amounts of rain on the country.
Gonaives, the worst hit city, remains mostly under water, hindering aid convoys in their efforts to deliver food.
Many thousands of people were forced to seek refuge on rooftops and balconies after the port city was submerged.
Help is arriving in the area, with UN troops picking people from rooftops and distributing some food.
Relief agencies say as many as 600,000 people throughout the country need assistance.
Safe drinking water is in short supply, and carcasses from drowned farm animals are strewn in the floodwaters.
Among those stranded was this pregnant woman.
The UN believes that unless there is an adequate response to the disaster there will be more instability in this impoverished country.
