Border Patrol sectors across the embattled southern border are already full as they scramble to deal with a new surge in illegal crossings -- with agents again encountering large groups of migrants seeking, and obtaining, entry to the United States.
A Customs and Border Protection (CBP) source tells Fox News that all four main Border Patrol sectors are either nearing full capacity or are already over capacity and that as of Thursday morning, there are 19,400 migrants in custody.
Fox was on the ground as huge groups of hundreds of illegal migrants, many of them wearing wristbands to show they had been smuggled by cartels, crossed into the U.S. One group consisted of several hundred migrants -- mostly family units and unaccompanied minors. A source told Fox that the majority are released into the U.S. with a court date.
