Fifteen people have been killed and 70 hurt after an overpass carrying Mexico City metro train cars collapsed on to a road on Monday night.
A dramatic video published on local channel Milenio TV shows the overpass of the metro’s 12 line collapsing on top of cars on to a road below.
Videos on TV and social media also showed emergency crews and firefighters combing through the wreckage looking for survivors.
Mexico City Mayor Claudia Sheinbaum said 15 people had been killed and a car was trapped under the rubble.
She said on Twitter: “Unfortunately there are dead and injured people. I am on site supporting the installation of the command centre.”
The city’s Comprehensive Risk Management and Civil Protection Agency had initially put the toll at 13 and 70 people injured.
The metro’s 12 line was built when Foreign Minister Marcelo Ebrard was mayor of Mexico City.
“What happened today with the Metro is a terrible tragedy. My solidarity with the victims and their families” he said on Twitter.
“Of course, the causes must be investigated and responsibilities defined. I reiterate I am at the disposal of authorities to help in whatever is necessary.”
The Mexico City Metro system has a total of 12 lines, officially known as the Sistema de Transporte Colectivo.
Line 12 was opened in 2012. On that Line, vendors are prohibited and passengers must have a card, not a paper ticket, to access the station.
The entire transit system for the city, usually abbreviated to STC, is the second largest metro system in North America after the New York City Subway.
