At least 13 people died and almost 100 were injured after a train derailed in Mexico's south-western Oaxaca region, the Mexican navy said. The train, which was travelling between the Gulf of Mexico and the Pacific Ocean, was carrying 241 passengers and nine crew members. A total of 98 were injured, of whom 36 were being treated in hospital, the navy reported. The train derailed as it rounded a bend near the town of Nizanda, prompting Mexico's Attorney General to confirm that an investigation was under way. Mexican President Claudia Sheinbaum noted that five of the injured individuals are in serious condition, and high-ranking officials are heading to the crash site. Images from the scene showed rescue workers assisting passengers from the train, which had veered off the tracks and partially tipped over a cliff. The Interoceanic train, which connects the Pacific port of Salina Cruz with Coatzacoalcos on the Gulf Coast, consisted of two locomotives and four passenger cars. Mexico's navy oversees the country's railway network. The Governor of Oaxaca, Salomón Jara Cruz, expressed significant sorrow over the tragedy and stated that local authorities are collaborating with federal agencies to aid the victims. The Interoceanic rail link, launched two years ago, aimed to enhance the region’s economy through strategic improvements in transportation and infrastructure. The government's initiative seeks to modernize rail connections and promote economic growth in southern Mexico.
