EAGLE PASS, Texas — The strong show of force that Mexican military and federal police displayed at the border last week in an effort to deter illegal migration was short-lived, as all signs of security forces have since vanished.

Mexican vehicles put on a show at the border Thursday following an agreement that Coahuila Gov. Miguel Ángel Riquelme Solís struck with Texas Gov. Greg Abbott days earlier, vowing to be more aggressive blocking migrants from making it to the river and streaming across into the United States.
