The Biden administration has been forced to respond to a crisis involving more than 10,000 Haitian migrants who crossed illegally from Mexico and assembled under and around a bridge in Del Rio, Texas.

Following reports and video footage showing thousands of mostly Haitian migrants setting up a tent city and casually walking across a dam to enter the U.S., the Defense Department announced late Friday it would begin flying the migrants back to Haiti.

“Details are yet to be finalized but will likely involve five to eight flights a day, according to the official with direct knowledge of the plans who was not authorized to discuss the matter publicly and spoke to The Associated Press on condition of anonymity,” The AP reported.
