Thousands of migrants, mostly Hondurans, have joined caravans in recent weeks in an effort to speed across Mexico to request refuge at the USA border.
Several dozen migrants, frustrated with being stuck at the Mexican border, Monday breached the fence in hopes of being allowed to apply for asylum after being arrested on the United States' side.
The six people are all part of the same family from Guatemala and included three children: a 2-year-old, a 7-year-old and a 10-year-old.
A border camera captured images of a family of six illegal immigrants surmounting the wall in Arizona, with the aid of another man.
While many ran to try to escape capture, most walked up to Border Patrol officers and surrendered.
But about 90 minutes later, she and her children were seen on the US side of the border, according to the report.
The inhospitable conditions have increased the apparent frustration of thousands of the caravaners, some of whom arrived at this Mexican border city two weeks ago.
The attempt to cross into the United States illegally came just days after the migrants were transferred from one temporary shelter to another after it had become unsanitary. U.S. Border Patrol agents had the territory between the two barriers heavily covered.
Some migrants are likely to be economic refugees without a strong asylum claim, but others tell stories of receiving politically motivated death threats in a region troubled by decades of instability and violence.
Plans for illegal crossings were curbed by the Trump administration's decision to send troops to protect the border and impose a new policy that requires every migrant seeking asylum to remain in Mexico, where their cases will be heard.
This is in large part because the caravan organizers promised them they could get into the USA and stay there as their asylum case was heard. USA officials said agents had been wounded or hit by migrants throwing stones. "Stand on my head!" one migrant said, egging his companion on. At least one mother with three children were among those who crossed over. They turned around and waved to those still on the Mexican side.
