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

The train, which was traveling between the Gulf of Mexico and the Pacific Ocean, was carrying 241 passengers and nine crew members.

A total of 98 were injured, with 36 of those hospitalized, the navy reported.

The train derailed as it rounded a bend near the town of Nizanda, prompting officials to announce an investigation led by Mexico's Attorney General.

Mexican President Claudia Sheinbaum stated that five of the injured individuals were in critical condition.

Sheinbaum noted that top-level officials, including the secretary of the navy, were heading to the crash site.

Photos from the incident show rescue personnel assisting passengers off the train, which had come off the tracks and tilted over a cliff edge.

The Interoceanic train, managed by the Mexican navy, connects the Pacific port of Salina Cruz with Coatzacoalcos on the Gulf Coast, featuring two locomotives and four passenger cars.

Oaxaca's governor, Salomón Jara Cruz, expressed 'deep regret' for the tragedy, confirming that state agencies are coordinating with federal authorities to provide assistance to those affected.

This railway line was inaugurated two years ago as part of an initiative by former President Andrés Manuel López Obrador aimed at boosting the region's economy.

The project intends to modernize rail links across the Isthmus of Tehuantepec, fostering development through expanded ports, railways, and industrial infrastructure in southern Mexico.
