Authorities in Mexico say a train has collided with a double-decker bus northwest of Mexico City, killing at least 10 people and injuring more than 40. The accident took place early Monday in the town of Atlacomulco.  The state of Mexico’s civil defense agency said via X that authorities were still working the site of the accident, in an industrial area. No details were immediately given about how it occurred. One video circulated on social platforms showed the bus in heavy traffic slowly moving across the train tracks when the fast-moving train suddenly appeared out of frame, ramming the bus at its midpoint.
