The death toll rose Monday to six in the derailment of a cargo train carrying some 250 Honduran migrants attempting to make their way to the United States, officials said. Mexico’s National Institute of Migration said that another five migrants were hospitalized with serious injuries suffered early Sunday as they rode on the roof of the train, or tied between the cars to stop themselves slipping onto the tracks. The dead migrants were between 19 and 58 years old. Rescue works were trying to move the eight derailed cars to see if any more people were trapped underneath.
