GRAPHIC-Truck Carrying 100 Illegals Overturns In Mexico Killing 52

At least 53 people have been killed and dozens more injured after the truck they were being transported in crashed in southern Mexico, authorities say.

More than 100 people, said to be migrants from Central America, were crammed into the truck's trailer when it rolled in the state of Chiapas.

Pictures from the crash scene show victims strewn across the road next to the overturned truck.

There were also rows of what appeared to be bodies covered in white sheets.

It is one of the worst accidents of its kind in Mexico, with at least 58 people injured, some seriously, said Luis Manuel Garcia, head of the Chiapas civil protection agency.

He said the victims included men, women and children. Their nationalities have not been confirmed, but local officials said most of the people on board were from Honduras and Guatemala.

The truck was reportedly speeding when it flipped on a sharp bend and hit a pedestrian bridge on the main road leading to the Chiapas state capital Tuxtla Gutiérrez.

Chiapas, which neighbors Guatemala, is a major transit point for illegals.
