US officials have moved thousands of migrants away from a Texas border town that has seen an influx of mostly Haitian migrants over the past week.
More than 10,000 people have gathered under a bridge connecting Del Rio in Texas to Mexico’s Ciudad Acuña.
Local officials have struggled to provide them with enough food or services.
Some 2,000 people were moved to immigration and processing stations on Friday.
The US government says it plans to fly the migrants back to where they began their journeys.
Flights are expected to start on Sunday, with the US currently negotiating returns with the countries in question.

The makeshift camp at Del Rio has few basic services, and migrants waiting in temperatures of 37C (99F), have been wading back across the river into Mexico to get supplies.
The migrants are mostly Haitians, with some Cubans, Peruvians, Venezuelans and Nicaraguans also present, reports say. Many Haitians left the country after a devastating earthquake in 2010, with many finding work in South America.
The migrants make the dangerous trek on foot, by car and bus to the US border – some crossing the Rio Grande.
The US government has been facing a surge of migrants at the border this year.
The number of migrants detained at the US-Mexico border in July exceeded 200,000 for the first time in 21 years, according to government data.
