Mexico says it has found migrants riding on about half of trains inspected south of the U.S. border.
While the largest number of migrants were detained while walking, a significant number were also found on buses or hidden in trucks.
Mexico’s government presented figures on its crackdown on migrants, which started in May.
Officials say Mexico had detained 178,917 migrants, mainly Central Americans as of nearly the end of 2019.
The country deported 84,327 migrants and has received 66,915 asylum claims as reported near the end of 2019.
