Of the 174 people intercepted, 159 are from Guatemala, 8 from Ecuador, 2 from El Salvador, 3 from Honduras and 1 from Pakistan. The migrants were traveling in a truck in the southeastern state of Chiapas.
The back door was closed and the driver refused to open it, but the faces of minors, women and men were visible through the awning. In December, 53 migrants were killed when a truck carrying them overturned in the same state, near the U.S. border.
