In Pictures: Mexico City metro overpass collapses onto road

An elevated section of the Mexico City metro collapsed and sent the train plunging towards a busy boulevard late on Monday, killing at least 23 people and injuring at least 79, city officials said. Rescuers found four bodies trapped inside a rail carriage that was dangling from the overpass but were unable to remove them. It was not clear if those dead were included among the 23. A crane was brought in on Tuesday to lower the carriage. Mayor Claudia Sheinbaum said one of the concrete beams collapsed as a subway train passed over it in one of the deadliest episodes in the history of the city’s subway system, which is among the busiest in the world.
