TUXTLA GUTIERREZ, Mexico — A cargo truck jammed with people who appeared to be Central American migrants rolled over and crashed into a pedestrian bridge over a highway in southern Mexico on Thursday, killing at least 53 people and injuring dozens more, authorities reported.
The federal Attorney General’s Office said the preliminary estimate lists 53 dead, with three of the injured in critical condition.
Luis Manuel Moreno, the head of the Chiapas state civil defense office, said about 21 of the injured had serious wounds and were taken to local hospitals.
The crash occurred on a highway leading toward the Chiapas state capital. Photos from the scene showed victims strewn across the pavement and inside the truck’s freight compartment.
Video footage showed the dead and injured migrants jumbled into a pile inside the collapsed freight container, with some struggling to extract themselves from the weight of bodies piled atop them.
Later, rescue workers arranged the dead in rows of white sheets, side by side, on the asphalt.
The victims appeared to be immigrants from Central America, though their nationalities had not yet been confirmed. Moreno reported that some of the survivors said they were from the neighboring country of Guatemala.
Sitting on the pavement beside the overturned trailer, survivor Celso Pacheco of Guatemala said the truck felt like it was speeding and then seemed to lose control under the weight of the migrants inside.
Pacheco said there were migrants from Guatemala and Honduras aboard and estimated there were eight to 10 young children. He said he was trying to reach the United States, but now he expected to be deported to Guatemala.
Rescue workers tried to excavate survivors from a pile of humanity in the flipped trailer, separating the injured from the dead. Dazed wounded stumbled among the wreckage.
Marco Antonio Sánchez, director of the Chiapas Firefighter Institute, said ambulances raced victims to three hospitals, carrying three to four injured each. When there weren’t enough ambulances they loaded them into pickup trucks, he said.
Guatemalan President Alejandro Giammattei wrote on Twitter: “I deeply regret the tragedy in Chiapas state, and I express my solidarity for the victims’ families, to whom we will offer all the necessary consular assistance, including repatriation.”
Moreno said that it appeared that speed and the weight of the truck’s human cargo may have caused it to tip over, and that as the vehicle toppled over it hit the base of a steel pedestrian bridge. There was a curve in the road near the accident scene that may have contributed to the crash.
That meant at least 107 people were crowed into the vehicle. It is not unusual for freight trucks in Mexico to be carrying so many people in migrant-smuggling operations in southern Mexico.
But rescue workers who first arrived at the scene said that even more migrants had been aboard the truck when it crashed and had fled for fear of being detained by immigration agents.
