People enjoy themselves as they dance to Dominican music at a refugee camp for Haitians returning from the Dominican Republic on the outskirts of Anse-a-Pitres, Haiti, September 6, 2015.

The program centers on round-ups and deportations that have triggered concerns about a slow-growing border migration crisis in the poorest country in the Americas. So far about 1,500 people have been deported at a pace of 50 to 100 per day, according to relief officials with access to records supplied by the Dominican government.
