The several thousand migrants traveling in a large group through southern Mexico toward the United States are expected to head to Del Rio, Texas, or Yuma, Arizona, according to two Border Patrol agents who have reviewed government intelligence reports.

The 2,000-3,000 migrants departed the Guatemala-Mexico border heading north on foot late last week. The group is first headed to Mexico City, an 800-mile journey that will take weeks to complete unless the migrants can find transportation. At present, the caravan of people has reportedly traveled 25 miles in four days.
