Last week, a huge group of illegal immigrants, all seeking asylum, tunneled under portions of a border barrier near San Luis, Arizona. They voluntarily surrendered to Customs and Border Protection.



ABC News has the story:

The largest single group of asylum seekers ever to cross into the U.S. tunneled beneath the border wall near San Luis, Arizona, on Monday, voluntarily turning themselves into Customs and Border Protection, according to the agency.

Migrants can be seen marching toward Border Patrol agents by the hundreds, according to video obtained by ABC News. Smugglers dug a series of seven holes, only a few feet long beneath the steel border fence, with hundreds going beneath the wall and a smaller number clambering over it, according to CBP.

The fresh sand and scuff marks of shoes on the rusty steel were still there when ABC News visited the site on Thursday.

The agency says 179 of the record 376 people who crossed were children, including over 30 unaccompanied minors — children under 18 traveling on their own.

The mass crossing this week took place in a sparsely populated stretch of the border — where an old model of border barrier rises about 12 feet from the sandy ground. The stretched agency only had three agents patrolling that 26-mile-long section of the border.

It took hours to process the families, most of which were sent to the area’s chronically overcrowded central processing center in Yuma.

“In my 30 years with the Border Patrol, I have not been part of arresting a group of 376 people,” Porvaznik said. “That’s really unheard of.”
