Migrants from El Salvador cross the border river between Guatemala and Mexico braving the waters of the Suchiate on foot on their trek north towards the United States.

This group set out from San Salvador earlier this week and is mostly made up of Salvadorans and some Guatemalans.

The larger group, which is currently in Mexico’s Veracruz State, originated in Honduras.

U.S. President Donald Trump has hardened his stance on immigration, and specifically against the caravan of migrants, ahead of next week’s congressional elections.
