At least 36 people were killed when a bus crashed into the back of a broken-down truck in Mexico and caught fire.
Mexican officials said four people survived the overnight crash with injuries in the southeastern state of Veracruz.
The accident happened near the city of Isla when a Turtle company bus heading from Villahermosa, the capital of Tabasco state, to Mexico City hit a truck that had stopped on the highway.
The truck belonged to Prolat, a company based in the city of Tepatitlan, Jalisco.
The tractor-trailer had experienced problems and did not have its hazard lights on.
Four people injured in the accident were transported to the Hospital Metropolitano in Acayucan, emergency management officials said.
Veracruz Gov. Javier Duarte visited the injured on Sunday and expressed his condolences to the relatives of the dead.
Tabasco Gov. Arturo Nuñez, for his part, visited accident survivors Manuel Quino Tejeda and his wife, Lucero Rodas Perez.
Quino Tejeda, who works in network systems security for Telefonos de Mexico, pulled his wife, a 19-year-old man and another unidentified person out of the burning wreckage.
The bus’s relief driver, who was sleeping in the rest compartment, apparently survived the crash.
