Fox News has obtained footage showing the moment a migrant caravan with more than 1,000 people crossed over the U.S.-Mexico border into El Paso, Texas.

The video, taken Sunday night, comes as U.S. Customs and Border Protection sources said Monday that its El Paso sector has seen 2,397 migrant encounters in the last 24 hours alone.

The city of El Paso has a dashboard that reports Border Patrol in that sector currently has around 5,100 migrants in custody.

"Customs and Border Protection’s El Paso Sector on the Texas border with Mexico has seen an increase in encounters," CBP said in a statement to Fox News on Monday afternoon. "In order to process individuals as safely and expeditiously as possible, Border Patrol agents from Big Bend and CBP Officers from El Paso Field Office are assisting with processing."

Officials have started mass releases of several hundred migrants to El Paso city streets.

Prior to these border crossings, Mexican police escorted nearly 20 buses full of migrants into the Mexican city of Ciudad Juarez, which is located across from El Paso. The police released the migrants to various non-governmental organizations.

The migrants then walked from the non-governmental organizations and crossed illegally into El Paso.
