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 had gathered under a bridge connecting Del Rio in Texas to Mexico's Ciudad Acuña.

Local officials have struggled to provide them with food and adequate sanitation.

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, BBC reported.

Flights are expected to start on Sunday, with the US currently negotiating returns with the countries in question.
