And Sunday, July 30, was the International Day Against Human Trafficking. Millions of people are trafficked each year as part of a multibillion-dollar industry. On Sunday, Mexican officials say they discovered more than 170 Central American refugees who had been abandoned by their traffickers in a trailer in the state of Veracruz as the men, women and children were attempting to traverse Mexico to reach the U.S. border. In Veracruz, local residents offered the refugees food and water. This is is Maria Elena Santiago.

Maria Elena Santiago: “There were young people, older men, women. They had brought children, small children, aged perhaps eight, nine, 10 years, around that age. The children they brought were also running. They wanted to eat, but the only thing we could do early in the morning was to provide coffee, milk and cookies. That is what we gave them.”
