TAPACHULA—More than a thousand migrants broke out of a detention center in southern Mexico on Thursday evening, authorities said, in a fresh sign of how a surge in arrivals has stretched the country’s resources to the limit.
More than half of the roughly 1,300 migrants later returned to the Siglo XXI facility in the border city of Tapachula in Chiapas state, but about 600 are still unaccounted for, the National Migration Institute said in a statement.
