(Washington Examiner) Mexican military deployed throughout the country as part of President Andrés Manuel López Obrador’s vow to do more to apprehend migrants headed to the United States, have officially begun targeting foreigners who have hitched rides aboard a freight train known as “The Beast” to get to the U.S.-Mexico border, local media reported Sunday.

Mexican National Guard held up the “La Bestia” train in an unpopulated area near Tuxtla Gutiérrez, Chiapas, a city north of the Mexico-Guatemala border, where migrants have been crossing into the country.

The operation marked the first of its kind since López Obrador and President Trump reached a deal late Friday, in which the U.S. would hold off on tariffs against Mexican imports if the government did more to prevent people from traveling through the country.
