ACUNA, Mexico—Some of the thousands of illegal immigrants who have amassed near the Texas border are leaving the United States, returning to Mexico to pick up supplies or to avoid being deported back to their home countries.
Haitians and others were witnessed on Sept. 20 crossing the Rio Grande to enter Acuña, Mexico, as they consider their options following a U.S. crackdown on the illegal immigrant camp under the International Bridge just north of the border in Del Rio, Texas.
