The president of Mexico, Claudia Sheinbaum Pardo, asked the Attorney General's Office and the Railway Transport Regulatory Agency (ARTF) to clarify “with great rigor” what happened in the derailment of the Interoceanic train that left 13 people dead in the state of Oaxaca.

“Second, to clarify, for this there are two institutions, to clarify with great rigor what happened. There are two institutions, the first is the Attorney General's Office, the State Attorney General's Office also participates… And also the train regulatory agency, or rather the Transportation Regulatory Agency, which is coordinated by Andres Lajous. He is required by law to conduct a review as well, but since in this case there were fatalities and injuries, the Attorney General's Office has to participate. The second very important thing is the rigorous analysis of what happened, what caused this accident,” she stated.

After offering her condolences and solidarity to the families of the victims of the accident, the Mexican president said that another priority is to guarantee the safety of the Interoceanic train so that it can continue operating.

“The third is to guarantee safety "The Interoceanic Railway is also under investigation by the agency, and we will review the situation with the Secretariat of the Navy to ensure that the track and everything else is in suitable condition to operate again," she commented. From the National Palace, Sheinbaum Pardo announced that she will travel to the Mexican state of Oaxaca to oversee the efforts to assist the victims of the accident. "The first priority is to guarantee the well-being of the victims and their families. Later, I will travel there to speak with the families," she stated.
