At least 20 people were killed, including children, and 49 were hospitalized when a railway overpass collapsed onto a busy road in Mexico City on Monday (May 3) night.
Rescue efforts for potential survivors were paused shortly after the accident, authorities said, because of the risk that more of the Metro overpass and train cars could slam down onto the road.
Sheinbaum said it appeared a girder had given way on the overpass but the cause was being investigated.
The Metro 12 line that runs over the collapsed overpass was built almost a decade ago when Foreign Minister Marcelo Ebrard was mayor of Mexico City.
INTERPRETER: Very sadly, too, there are 20 people who have died at this point.
We have identified 38 of those who have been taken to hospital.
And I want to say to families that are listening that if they believe that any members of their families was on the train, we have an emergency post here and there is one in each of the hospitals for families.
As feared, the 20 people who, very sadly, have been killed include some young people, Although, unfortunately, we can't say how many at this point.
At this point, we still have not identified those who are trapped, but rest assured that the Secretary of the Navy and all his team and the Civil protection team, as well as firefighters, of course, are doing everything they can to see if they can identify any further people.
