At least 13 people died and almost 100 were injured in a train derailment in Mexico's south-eastern Oaxaca region, according to reports from the Mexican navy.

The Interoceanic train, which was en route between the Gulf of Mexico and the Pacific Ocean, carried 241 passengers and nine crew members. The navy reports that 98 individuals suffered injuries, with 36 currently receiving treatment in hospitals.

The derailment occurred when the train rounded a bend near the town of Nizanda. Officials from Mexico's Attorney General's office have confirmed that an investigation is underway to determine the cause of the incident.

Mexican President Claudia Sheinbaum stated that five of the injured individuals are in serious condition. Key officials, including the Secretary of the Navy, are heading to the scene of the crash to assist in the response.

Images from the derailment site depicted rescue workers aiding passengers who were evacuated from the train, which partially tilted off the tracks and over the edge of a cliff.

The Interoceanic rail service, initiated two years ago under the direction of former President Andrés Manuel López Obrador, was designed to enhance the region's connectivity and stimulate economic growth by linking the Pacific port of Salina Cruz with the Gulf Coast port of Coatzacoalcos.

Governor of Oaxaca, Salomón Jara Cruz, expressed his profound regret regarding the tragic incident, highlighting that state authorities are working closely with federal agencies to provide support to victims and their families.
