The Mexican National Guard intercepted two trucks transporting 243 migrants in crowded conditions in the southern state of Chiapas.
Federal authorities stopped the two trucks in separate incidents Thursday, detaining 125 migrants, including 24 children, from Central America in the first traffic stop on a highway connecting the cities of Teapa–El Escopetazo.
According to a government statement, the first group consisted of 108 Guatemalans, 15 Salvadorans and two Hondurans.
Law enforcement agents also detained two individuals, whose identities were not provided, for trafficking the undocumented immigrants, who were screaming for help once the National Guardsmen approached the truck.
A second operation during a checkpoint on a road that connects the municipalities of Las Choapas–Ocozocoautla led the National Guard to 118 Central American migrants.
The Mexican troops listed 99 nationals from Guatemalan among the group that was rescued, which was accompanied by 14 migrants from El Salvador and five from Honduras.
The National Guard also arrested two individuals for illegally transporting the migrants.
In both instances, the migrants showed signs of dehydration and were treated and delivered to the custody of the National Migration Institute.
All four suspected traffickers were placed under the custody of the Federal Public Ministry.
Mexico has ramped up efforts to stem migration through its territory in recent months under pressure from Washington after President Donald Trump threatened his Mexican counterpart, Andrés Manuel López Obrador, with import tariffs.
In exchange, the leftist leader promised Trump place 6,000 National Guard soldiers to Mexico’s southern border with Guatemala to curb the flow of migrants coming through the country as part of a June 7 immigration accord with the U.S.
López Obrador also dispatched some 15,000 soldiers to its northern border with the U.S. to detain migrants trying to cross illegally.
Authorities say people-smuggling is a key area of emphasis for the joint-nation crackdown.
