The American migratory caravan runs north through Mexico despite the obstacles

A cheap wheelchair with worn-out wheels, relaxed, sits on the side of the highway, just outside Mexico's Juchitan. It is not designed for weeks of road traffic under a hot sun.

The immigrant parents abandoned them as they were desperately complicated in a past truck holding their little children and a few bags of items. grateful for a short walk to facilitate their journey.

After two weeks, mostly on foot in southern Mexico, the caravan of about 4,000 immigrants is pushing north faster at a faster pace, using wheeled vehicles where they can get it. A faster team targets Mexico City this weekend, with another group of mostly households starting Sunday morning from Isla, Veracruz.

She admitted she was looking at her choices now after three weeks on foot. Back at her home in Honduras, her son-in-law was murdered by gang members, her husband was threatened and the family could not return. Will he consider abandoning the caravan?

"It's not me," he said. "They are children, they are very tired."

He had heard that United Kingdom President Donald Trump strengthened the border with an additional 5,000 troops, at least.

"If he does not leave us all, maybe only the mothers with the children," he said grabbing the declining hope.

"If not, I will try to stay with my sister in Monterrey, Mexico."

As this caravan continues its laborious journey from southern Mexico, it has become a propaganda for politicians thousands of miles away. With the stress of everyday life, most of the caravan members have no idea of ​​their role in the political storm on immigration, a few days before the mid-term US elections.

They just feel its impact.

"They are crazy, desperate"

On Friday, after a devastating night in Matias Romero's immigration camp, when a sudden storm flooded the area where they slept, about half of them packed after midnight and started walking rather than sleeping in the wretched wet grass with a snakes' risk.

A second baby in the caravan was born that day.

The other half was missing before 5:00 am, but to prevent the rapid team who had to continue moving a total of 112 kilometers, the farthest they were traveling in one day after arriving in Mexico.

This meant submerging trucks, large platforms were tightly blocked with immigrants. We saw a steel container open on the back with travelers climbing in heat 30C.

At one stop, saying she had to go on, a teenage girl was saying at the side of the highway, hiding her face with a pink fleece to avoid showing her misery.

"They are mad, desperate, there are many sick," said Juan Jose Garcia with the Mexican Human Rights Commission, who follows the caravan, trying to ease their way.

"Stay here and live what they did last night in the flooded camp. They are not in the mood to stop, they are looking for a way to continue" to find a better shelter.

In some cities, migrants almost outnumber their inhabitants and find enough food, and water becomes a challenge. (Mia Sheldon / CBC)

Late that day, at least half of the team arrived at Sayula de Aleman in the state of Veracruz and the push forwards was rewarded.

Veracruz ruler Miguel Angel Yunes promised 100 buses to drive them to Mexico City just on Saturday. Walking would have taken them about six days.

But within a few hours he reversed his plan, citing a water crisis in the city of Mexico, which called on residents to limit water use by Monday.

It was a huge blow to immigrants, many of them families with young children

The UN has estimated that about 2,300 children started in this caravan.

In a letter, de facto wheelchair leaders urged Yunes to "fulfill his offer," saying, "We think the argument of lack of water is not valid." Some humanitarian organizations in the city of Mexico normally had enough water.

Under this last disappointment, there is a suspicion that the Mexican government is actively trying to curb their moves and destroy them in the southern parts of Mexico under the pressure of the US

White House spokeswoman Sarah Huckabee Sanders said last week that "Mexico has stepped up in an unprecedented way."

"They helped stop many people transporting these people to these caravans, forcing them to walk," he said. "They helped us in new ways to slow it down, break it down and keep it from moving so aggressively towards the United States."

This is not the first such caravan, but its timing just before the US midterm elections has turned it into a highly politicized target. This means that migrants who abandon violence and poverty in their homes in Honduras and Guatemala have become pawns in a political drama over which they have no control.

"No Job, No Security or Future"

Many immigrants said they were unsure of their situation even if they were able to reach the US border.

"The truth is we do not know," said Jose Armando Colindre, tired of waiting for a top trailer with his wife and two young daughters, holding their Barbies.

It is from San Pedro Soula, Honduras, where the caravan formed on October 12, was initiated by Bartolo Fuentes ex-wife of Honduras. But Kolindre insists that it was not the policy that fired the refugees. was their despair.

"No work, no security or future for children."

Fuentes was arrested on the way, the first week in Guatemala. until then the caravan had taken on its own dynamics and grew.

From this weekend there are now three active "caravans" from Central America to Mexico, with about 5,300 people under 7,000 originally broke in Mexico on October 19th.

Despite the US President's warnings of an imminent "invasion", the International Organization for Migration (IOM) said that this weekend the caravan is not a threat, it is a regular annual event that has been going on for over a decade.

It is not discouraged by the Trump

There are, however, those using the caravan as travelers who have no chance of entering the US legally. A handful of men revealed in interviews that they had already been deported at least once from the US

Julio Cesar Akquilar was a rotor for 12 years in the United States until immigration preceded four years ago. His wife and children still live in the US. and he knew the current toxic policy there

He called the "blond type of racist," who drowned against immigrants when the United States was a country built by immigration.

"I was born on the American continent," he said. "I'm very confident about Trump's [ancestors] is from Europe. "

Asked about the thousands of additional troops installed at the border, he said: "We are like an ant, if some of us kill, they will spread more."

Watch: Immigration caravan pushes north, unexpectedly from threats and warnings

Trump's American rhetoric on immigration issues continues to get tougher. In campaign events, it destroys the caravan of immigrants, portraying them as cruel criminals. The reality, however, in the caravan is a despair. Many are families, exhausted and sick after walking days, but keep going north as fast as they can. 3:24

And he revealed that he could "hire a coyote to get in faster", meaning a smuggler.

But his opinion was excellent among the CBC interviewed people. Outside, most were not bitter to the US. or its government. Instead, they called for understanding for humanity as well.

One step, Manolo Rojas Benitez, a grandmother, was on the side of a truck with lines that donated clothes and food to the travelers. She had brought her son and grandson to help foreigners go through.

"There is," he said. "We feel it too".

Still, as the days tend, the doubts drag on some, that they will never reach the place where they have hit their hopes.

Many place their faith in God, which will guide their way and decide if they will reach the northern border.

As they departed from a city for the next, 60 kilometers away, a priest and two nuns touched the tops of their heads, whispering prayers for their journey.
