A caravan of Central American migrants on the move in Mexico is traveling closer to the southern borders of the United States despite warnings by President Donald Trump’s administration to block its way and attempts by Mexico to frustrate its advance.

The migrants continued their march toward the US by hitchhiking and walking along highways on Saturday.

Reports said the caravan of an estimated 4,000 Central American migrants had now advanced into the Mexican state of Veracruz, just one Mexican state away from the southern US state of Texas.

The caravan continued its travel to the US on foot after Mexico canceled a plan to provide the migrant group with transportation.

Veracruz Governor Miguel Angel Yunes had announced on Friday that authorities in the Mexican state would be providing not only humanitarian assistance to the migrants but also dozens of passenger buses to quickly transport them to the country’s capital, Mexico City, “or to the place they wish.”
