Caravan of 2,000 Migrants Detained in Southern Mexico Associated Press TAPACHULA, MEXICO - Mexican officials broke up a caravan of around 2,000 migrants that had set out from southern Mexico Saturday in the hopes of reaching the United States, amid increasing difficulty obtaining permission to pass through Mexico. Many of the migrants who departed from Tapachula, Chiapas, early in the morning had been held up in this city just north of Guatemala for weeks or months, awaiting residency or transit papers from Mexican authorities. The migrants are originally from Central America, Africa and the Caribbean. They left their home countries sometimes because of violence, or simply in search of a better life. .
