The caravan left Tapachula, on Mexico's border with Guatemala, on Sunday and arrived around 12:00 p.m. (local time) in Huixtla, where they encountered a military wall at the main access to the CAIFT.

National Guard member Victor Manuel Hernandez informed the migrants that the authorities of the National Migration Institute (INM) were not going to attend to their demands at that time.

Because of this, the migrants insisted on receiving attention, they proceeded to settle outside the migratory point in small groups awaiting a favorable response. 

Keider Escalona, a migrant from Venezuela, criticized the country's authorities because they are putting many obstacles to be able to leave.

"It has been very difficult for not having money and not having a family to send me to be able to pass, it has been difficult, the only way we have been able to pass freely is through this concentration with much effort," he told Efe.

The migrants who are part of the caravan expressed their physical exhaustion, some with despair to continue because the Mexican authorities do not listen to them.

"We are quite exhausted, injured, the children are sick with fever, it has rained in the middle of the walk, we have had support only from journalists. We demand that they facilitate our access to the permits for Monterrey (city in the north of Mexico)", said Eduardo Balero, another Venezuelan migrant.

Some groups took buses to continue moving towards the state of Oaxaca, leaving behind the most vulnerable, such as women and children.

The Mexican government has received multiple criticisms for its treatment of migrants, including the deployment of almost 30,000 members of the Armed Forces on its northern and southern borders for migration tasks.
