At least 23 people were killed and 65 were hospitalized when a railway overpass and train collapsed onto a busy road in Mexico City on Monday night, crushing cars under fallen carriages and rubble. The authorities halted rescue efforts shortly after they began, saying there was a risk that more train parts and debris could slam down onto the road. Speaking to reporters at the site, Mexico City Mayor Claudia Sheinbaum said it appeared a girder had given way on the overpass but the cause was being investigated. Source: Reuters
