The death toll from the collapse of an overpass on the Mexico City metro rose to 24 on Tuesday as crews untangled train carriages from the steel and concrete wreckage that fell onto a road beneath.

Another 77 people were injured when the support beams collapsed at about 10:30pm on Monday as a train passed along the elevated section, said Mayor Claudia Sheinbaum in describing one of the deadliest incidents in the history of the subway system, one of the world’s busiest.
