Hundreds of Central American migrants crossed the Guatemala-Mexico border at dawn Thursday without resistance and began walking up a rural highway.

Some carried banners arguing that migrants were not the problem, but rather the result of poor governing.

Mexico began flying and busing members of the caravan back to Honduras on Tuesday.

Seven more buses left Mexico for Honduras on Wednesday, carrying 240 migrants back home, and two flights left with an additional 220 Hondurans, Mexico's National Immigration Institute said. By Wednesday, the number of people outside the Casa del Migrante in Tecun Uman was perhaps half of what it was at its peak Sunday night.

In previous caravans, Mexican authorities have allowed caravans to walk for awhile, seemingly to tire them out, and then closed their path.
