Detained immigrant children line up in the cafeteria at the Karnes County Residential Center, a temporary home for immigrant women and children detained at the border, Wednesday, Sept. 10, 2014, in Karnes City, Texas. Federal authorities want to build a similar immigration lockup facility for families in Dilley, Texas, south of San Antonio amid an unprecedented surge in the number of youngsters pouring across the U.S. border, a federal official said Thursday.
