The number of children who are caught trying to slip across the U.S.-Mexico border alone and illegally has quietly surged again more than a year after President Obama referred to the problem as an “urgent humanitarian situation.”

While the world has been focused on Europe’s migrant crisis, apprehensions of unaccompanied minors along America’s own border have exploded: More than 10,000 undocumented children have been stopped in just the last two months, according to U.S. Border and Customs Protection.

The 10,588 apprehensions are a 106 percent increase over the same Oct. 1 through Nov. 30 period from last year, when 5,129 kids were picked up.

Apprehensions of family units — legal guardians with children under 18 — have proliferated too, with 12,505 detentions in those two months, representing a 173 percent increase from last year’s 4,577 seizures in the same time frame.
