The caravan of migrants headed towards the U.S. southern border includes roughly 7,500 people from 24 different countries, according to a report from NBC News.
The caravan is headed through the Mexican state of Chiapas on the border of Guatemala, an organizer of the migrant caravan told the outlet.
The countries represented include Cuba, Venezuela, Syria, and Turkey.
Secretary of State Antony Blinken and Homeland Security chief Alejandro Mayorkas are expected to discuss immigration with Mexican President Andres Manuel Lopez Obrador Wednesday.
According to a statement from State Department spokesman Matthew Miller, the officials will discuss "unprecedented irregular migration in the Western Hemisphere and identify ways Mexico and the United States will address border security challenges."
Activist Luis García Villagrán told NBC News that some of the migrants aren't seeking to get into the U.S., but plan to stay in Mexico.
“The conditions in which the companions, the migrant women and children, are walking is truly deplorable,” he told the outlet.
