400 Migrants Overwhelmed US Border In Yuma Sector During Week-Long Period

Nearly 400 migrants traveled underground Monday through a series of tunnels built by smugglers before turning themselves in to Customs and Border Protection (CBP) in what appears to be the largest single group of migrants ever attempting to seek asylum.

Smugglers dug a series of seven holes just a few feet beneath the steel border near San Luis, Arizona, ABC News reported. Hundreds of asylum seekers went under with a few attempting to climb over the 12-foot wall.

Of the 179 minors in the group, Newsweek reported, 30 of them were unaccompanied.

Another 247 migrants crossed the border Wednesday by the Antelope Wells Port of Entry and entered New Mexico; Both groups voluntarily turned themselves in.

“In my 30 years with the Border Patrol, I have not been part of arresting a group of 376 people,” CBP Yuma Border Sector Chief Anthony Porvaznik told ABC News. “That’s really unheard of.”

Porvaznik said that while his team needs stronger barriers, its foremost concern right now is having enough funding to take care of the families that crossed over.

“That’s our No. 1 challenge that we have here in the Yuma sector, is the humanitarian problem,” he told ABC News. “As I mentioned, 87 percent of the apprehensions here are family units and unaccompanied alien children.”
