As a group from Central America heads to the border between the U.S. and Mexico, the Trump administration is said to be getting ready to send troops to meet them and Catholic groups are asking that the migrants be treated humanely.

Members of St. Francis of Assisi Parish in this southern Mexican city rose early Oct. 24 to feed but a fraction of the Central American migrants traveling in a caravan, which is trying to traverse Mexico and reach the United States border.

The group, many with children and even pushing toddlers in strollers, departed Mapastepec at dawn with more than 1,000 miles still to go before they reach the U.S. border.

Vatican official says people must not succumb to fear mongering and realize that the challenge of migration today is solvable—but only if there is political will.

Many of the migrants in the caravan are fleeing Central America’s “Northern Triangle”—El Salvador, Guatemala and Honduras. These countries are beset by “the world’s highest murder rates, deaths linked to drug trafficking and organized crime and endemic poverty.”
