MEXICO CITY (AP) — A cargo train derailed in southern Mexico without causing any injuries to about 1,300 Central American migrants who had jammed onto the freight cars on their way north toward the United States, authorities said Thursday.

Luis Velasco, spokesman for the Oaxaca state civil protection agency, said the train was delayed for several hours until workers could repair the rails late Wednesday. He said it was traveling from Arriaga in neighboring Chiapas state to the Oaxaca city of Ixtepec, a common route for Central American migrants.
