MAPASTEPEC, Mexico (Reuters) - Mexican immigration agents and security forces stepped up efforts to halt the progress of a caravan of hundreds of Central American and Caribbean migrants as they moved toward Mexico City from southern Mexico on Tuesday.
Entire migrant families including many with young children arrived at two towns in the southern state of Chiapas, Mapastepec and Escuintla, after passing through the Mexican town of Tapachula near the Guatemalan border, according to Reuters witnesses.
