Mexico’s top diplomat, Alicia Barcena, reported that in September, 60,000 Venezuelan migrants, 35,000 Guatemalan migrants, and 27,000 Honduran migrants arrived in the country.

This data comes ahead of a migration summit in Palenque, hosted by President Andres Manuel Lopez Obrador, where regional leaders will discuss rising U.S.-bound migration in Latin America. Colombia’s Gustavo Petro and Venezuela’s Nicolas Maduro are among the confirmed attendees.

The number of migrants crossing Mexican territory has risen since May after US authorities authorized more legal pathways to enter the US. Approximately 1.13 million migrants have reached Mexico’s southern border with Guatemala this year, while 1.75 million have reached the U.S.-Mexico border. About 63,000 migrant children have arrived in Mexico since August, with 7% unaccompanied and nearly three-quarters aged 11 or younger.
