MEXICO CITY—The unprecedented wave of Haitian migrants at the U.S. southern border is causing a crisis in Mexico, which now must contend with thousands of asylum seekers turned back by the U.S.
The migrants have been streaming back into Mexico from Del Rio, Texas, where as many as 16,000 had gathered in recent days under a bridge on the U.S. side. As American officials this week began rounding up hundreds of the Haitians and deporting them to Haiti on aircraft, many who remained returned to the Mexican side to avoid being sent back to their impoverished and chaotic nation.
