The Mexican government suffered a backlash over the migrant arrests and detentions the northern border. The criticisms were triggered by a photograph last week, which showed heavily armed National Guardsmen preventing women and a child from crossing the Rio Grande River into the United States.
In the past, Mexican forces were not arresting and detaining migrants at its northern border. Its policy changed due to pressure from the Trump administration.
Central American migrants are trying to escape poverty and gang violence in their home countries. They are taking the big risks of traveling without migration papers through Mexico to the United States to seek asylum.
