At least 24 people were killed and 70 others hurt when a Mexico City Metro rail overpass collapsed onto a road Monday night right as a train was passing overhead, Mexican authorities said. "A support beam gave way" on the Metro 12 line overpass, Mexico City Mayor Claudia Sheinbaum said. President Andrés Manuel López Obrador vowed that a thorough investigation would be carried out. As of Tuesday afternoon only five of the dead have been identified; a car was trapped beneath rubble and the train split in two and was suspended precariously, hindering rescue efforts. This is the third serious accident on the five-decade-old Mexico City Metro, one of the largest and busiest commuter rail systems in the world. The other two, in 2015 and 2019, involved two trains colliding.
