MATIAS ROMERO, Mexico — The caravan of Central American migrants that angered US President Donald Trump was sidelined at a sports field in southern Mexico with no means of reaching the border even as Trump tweeted another threat to Mexico on Tuesday. “The big Caravan of People from Honduras, now coming across Mexico and heading to our “Weak Laws” Border, had better be stopped before it gets there,” Trump wrote. “Cash cow NAFTA is in play, as is foreign aid to Honduras and the countries that allow this to happen.” The caravan that once numbered 1,150 or more people actually halted days ago in the town of Matias Romero in the southern state of Oaxaca. On Tuesday, the group — mostly Hondurans — that had been walking along roadsides and train tracks prepared meager breakfasts with donated food. They were getting advice from Mexican immigration officials on filing for temporary transit or humanitarian visas in Mexico. A couple hundred men did break off from the march on Sunday, hopping a freight train north, probably with hopes of trying to enter the US. But the rest seemed unlikely to move again until Wednesday or Thursday, and they probably would take buses to the last scheduled stop for the caravan, a migrant rights symposium in the central state of Puebla. Irineo Mujica, director of Pueblo Sin Fronteras, the activist group behind the annual symbolic event designed to draw attention to the plight of migrants, said the caravan would continue only to Puebla southeast of Mexico City, “but not in a massive way.” After the symposium, some migrants might go to Mexico’s capital, where it is easier to make an asylum claim. Mujica said about 300 to 400 say they have relatives living in Mexico and so may consider staying here at least temporarily. There were reports Mexican officials were seeking to end the caravan, but it was for all intents and purposes over anyway. The participants were never equipped to march en masse to the US border or anywhere near it. The “Stations of the Cross” caravans have been held annually in southern Mexico for about 10 years. They began as short processions of migrants, some dressed in biblical garb and carrying crosses, as an Easter-season protest against the kidnappings, extortion, beatings and killings suffered by many Central American migrants as they cross Mexico. The organized portions of the caravans usually have not gone much farther north than the Gulf coast state of Veracruz, although some participants have then gone off by bus or truck to the US border, moving as individuals or in small groups. This year’s event seems to have gotten more notice in the US, and Trump has sent some angry tweets that raised hackles in Mexico, which in recent years has detained and deported hundreds of thousands of Central American migrants before they could reach the US border. “Mexico is doing very little, if not NOTHING, at stopping people from flowing into Mexico through their Southern Border, and then into the US. They laugh at our dumb immigration laws. They must stop the big drug and people flows, or I will stop their cash cow, NAFTA. NEED WALL!” Trump wrote in one. “With all of the money they make from the US, hopefully they will stop people from coming through their country and into ours.” Mexico’s interior secretary, Alfonso Navarrete Prida, rejected such pressure. “We will act with complete sovereignty in enforcing our laws,” he said on Monday. “Of course we will act ... to enforce our immigration laws, with no pressure whatsoever from any country whatsoever.” In a statement late Monday, Mexico’s government said about 400 participants in the caravan had already been sent back to their home countries. “Under no circumstances does the Mexican government promote irregular migration,” the Interior Ministry statement said. But it added that Mexico considers the annual caravans to be “a public demonstration that seeks to call attention to the migration phenomenon and the importance of respecting the rights of Central Americans.” The US government has been kept fully informed of the situation, it said. The department also said that unlike in previous yearly caravans, “this time Mexican immigration authorities have offered refugee status” to participants who qualify. But it suggested it is not up to Mexico to keep people from going to the US to apply for asylum. “It is not this government’s responsibility to make immigration decisions for the United States or any other country, so it will be up to the appropriate authorities of the United States to decide whether to authorize the entry of the caravan participants to US territory,” the statement said. — AP
