Thousands of Central American migrants are pushing more quickly through Mexico in the hopes of fulfilling their dream of reaching the United States.

The majority of the roughly 4,000 migrants are headed Sunday toward the town of Cordoba, Veracruz, which is about 124 miles (200 kilometers) up the road. The daily trek will be one of the longest yet, as the exhausted group of travelers tries to make progress any way they can.

The journey now appears to be taking its toll.

A day prior, the group was beset by divisions as some migrants argued with caravan organizers and criticized Mexican officials before setting out on their own toward Puebla and Mexico City. Many are fighting off blistered feet and coughs.

It remained to be seen if the main contingent will continue directly north through the Gulf coast state of Veracruz or veer slightly westward and make a stop in the country's capital.

Mynor Chavez is a 19-year-old migrant who said he could not get ahead in his home country.

"I have no hope. I graduated as a computer technician and not even with a degree have I been able to find work," he said.
