More than 10,000 migrants packed under Texas bridge, number still rising

More than 10,000 migrants, most of them Haitian, are packed under an overpass bridge in Del Rio, Texas, as U.S. border agents struggle to keep up with the surge in the area, according to two senior Department of Homeland Security officials.

Many of the Haitian migrants have not come directly from the island nation to the U.S., but rather have been living in South America and have been brought to Del Rio along a common smuggling route used by a Mexican cartel, the officials said.

The numbers under the bridge have ballooned over the past 48 hours, growing from around 5,000 on Wednesday and are expected to rise above 11,000 on Friday, they said.

Migrants arriving at the makeshift processing center under the bridge are given emergency supplies like water and infant formula and are processed before being taken to a Border Patrol station or Immigration and Customs Enforcement custody.
