In Overwhelmed Del Rio, Texas, Migrants Cross the Border Freely

DEL RIO, Texas and CIUDAD ACUÑA, Mexico—Jorge Rios stood watch at his family’s property on the Mexican side of the border between these two cities Saturday while a stream of migrants trudged back-and-forth across the Rio Grande. Many held boxes or bags above their heads as they waded through the murky, thigh-high water. Some carried frightened-looking children.

“It’s like a road. Just people, people, people,” said Mr. Rios, 28.
