TAPACHULA, Mexico (Reuters) - U.S.-bound migrants, mostly from Central America and the Caribbean, said on Thursday that a Mexican government crackdown was keeping them "prisoner" in the south of the country.

The migrant comments contrasted with Mexican President Andres Manuel Lopez Obrador's promises of humane treatment ahead of Thursday's high-level meeting between Mexican and U.S. officials in Washington, where the two countries agreed that development of poor regions was a long-term solution to slow migration north.
