The Border Patrol has stopped sending unaccompanied immigrant children caught crossing the Mexican border into Texas illegally to a processing center in Nogales, Ariz.

The massive warehouse where more than 1,000 migrant children once stayed now only has about 200 kids.

Border patrol officials are reporting far fewer children crossers in the past few days than the agency has seen in the past two months.

More than 57,000 children have crossed the border alone since October, creating what many called a humanitarian crisis and sparking a national debate about how to handle the situation.

In south Texas, only about 80 unaccompanied minors were detained Wednesday, compared to 200 to 300 arrests daily at the height of the surge.
