A large group of mostly Honduran refugees, reportedly numbering into the thousands, has crossed into Guatemala in a caravan that is believed headed to the U.S. border.

Hundreds of migrants have arrived at the Guatemalan border town of Tecún Umán, along the southern border of Mexico, James Fredrick reports for NPR. Organizers of the caravan say they are waiting for thousands more to join them in the coming days, before attempting to cross the Mexican border.

Mexico has ramped up security along its southern border and says that only migrants with valid paperwork will be allowed to enter Mexico — namely, a passport, which most of those in the caravan do not have.
