Mexican authorities have launched operations to block Central American migrants from illegally heading to the United States, stopping them from hitching rides on a freight train known as “The Beast.”
The operations came after officials pledged to take action to stem a wave of unaccompanied child migrants who have flooded into the United States in record numbers in recent months.
Migrant rights activists and a consular official from a Central American nation said Mexican federal police and immigration agents conducted patrols late Thursday along the train tracks in the southern state of Chiapas, which borders Guatemala.
