Drone video shows migrants under Texas bridge
Hundreds more are heading towards the border in a growing humanitarian and political challenge for U.S. President Joe Biden.
The Department of Homeland Security said some 2,000 people had been moved to other immigration processing stations on Friday.
DHS said in response to the migrants sheltering in increasingly poor condition under the Del Rio International Bridge, that connects the Texas city with Ciudad Acuna in Mexico, it is accelerating flights to Haiti and other destinations within the next 72 hours.
It added that it is working with nations where the migrants began their journeys to accept their return.
