CHONTALPA, Mexico (AP) — Officials say the death toll has risen to six in the derailment of a cargo train carrying at least 250 Honduran migrants trying to make their way to the United States.

Mexico's National Institute of Migration said Monday that another five migrants were hospitalized with serious injuries suffered early Sunday morning as they rode on the roof of the train, or tied between the cars to keep from slipping onto the tracks.

The dead migrants were between 19 and 58 years old.

Rescue workers were trying to move the eight derailed cars Monday morning to see if any more people were trapped underneath.
