SAN PEDRO SULA, HONDURAS — A massive caravan of migrants fleeing violence and poverty in Central America are marching north to the United States.

The New York Times reports that the migrant caravan started in San Pedro Sula, Honduras on October 12, with less than 200 people. Upon reaching Esquipulas, Guatemala, police blocked them for two hours but eventually allowed them to continue on.

The group's numbers swelled to over 7,000 as the journey from Honduras continued through Guatemala and to the Mexican border.

Mexico initially ordered migrants to submit to processing at a legal border crossing, but many have crossed illegally, storming through the border gate on October 19 and clashing with Mexican federal police.

The caravan is currently walking through Mexico, with over 1,000 miles to go before they can reach the United States border.

President Trump has been very vocal about his condemnations of the caravan, and has threatening to have the military close the border on them.

He has also threatened to cut off aid to Guatemala, Honduras, and El Salvador for not stopping their people from leaving their countries.
