MATIAS ROMERO, Mexico, April 5 (Reuters) - Impoverished Central American migrants traveling in a "caravan" through Mexico that angered U.S. President Donald Trump said they would stick together for safety even though the group will ends its journey in Mexico City rather than the U.S. border.
Since peaking at around 1,500 people, the caravan has dwindled under pressure from Trump and Mexican migration authorities, which vowed to separate those migrants with a right to stay in Mexico from those who did not.
By Thursday morning, scores of migrants were boarding buses to leave the town of Matias Romero in the southern state of Oaxaca, where their journey was held up by authorities at the weekend.
Salvadoran Andres Rodriguez, 51, stood with a small backpack and a gallon of water in a field sprawling with men, women and children, mulling over a document that gave him 20 days to reach any border out of the country.
Despite knowing the permit protected him from arrest and deportation, and that traveling alone is faster, he feared if he left the caravan he would be exposed to the robbery and assault that befall many migrants on the long slog to the U.S. border.
"It's much safer," he said. "Everyone is supporting us. One person alone is much more vulnerable. Much more dangerous."
Rodriguez, a builder, said he fled his home in El Salvador in the middle of the night, with only the clothes on his back, a few dollars, a nephew and his son, a student who had received a written death threat from a gang he had refused to join or pay.
"To be young, in my country, is a crime," Rodriguez said.
"I'm old - they'll do nothing to me. But to my son, if we go back ... they'll kill him."
Plagued by gang violence and poverty, El Salvador and neighboring Honduras have murder rates that are among the world's highest.
Stranded in Matias Romero since Sunday, some migrants began boarding buses before dawn on Thursday, headed for the central city of Puebla, where the caravan was due to make another stop before concluding its journey in Mexico City.
By mid-morning, others packed bags in a field strewn with discarded clothes and trash as two more buses waited.
Organized by advocacy group Pueblo Sin Fronteras, the caravan, which set off from Mexico's southern border on March 25, aims to raise awareness about the plight of migrants, and has been running annually since 2010, according to the government.
Trump's tweets criticizing the caravan have showered it in far more publicity than organizers expected. On Thursday morning the U.S. president praised Mexico on Twitter for breaking it up, hailing the country's "strong immigration laws."
Once in Puebla, organizers plan to hold a three-day conference with U.S. and Mexican immigration attorneys.
On a street just outside the park, 30-year-old Guatemalan Manuel Flores brandished a freshly issued temporary Mexican visa, but said he would stay with the caravan regardless. "I don't even need to be here, but I'm staying for them - for my family. Because they need this. They can't go home," he said, pointing to a group of newfound friends from Honduras and El Salvador, with whom he had cooked a great vat of seafood soup.
Bonded by the travails of their odyssey, they were already discussing setting up a restaurant in Texas together.
