TAPACHULA, Mexico—A sprawling caravan of migrants from Central America, Venezuela, Cuba, and other countries trekked through Mexico on Sunday, heading toward the U.S. border. The procession came just days before Secretary of State Antony Blinken arrives in Mexico City to hammer out new agreements to control the surge of migrants seeking entry into the United States.
The caravan, estimated at around 6,000 people, many of them families with young children, is the largest in more than a year, a clear indication that joint efforts by the Biden administration and President Andrés Manuel López Obrador’s government to deter migration are falling short.
