At least 23 people have died in Mexico City after an elevated train line collapsed Monday night, according to local officials.
The subway train running on Line 12 fell to the ground after a passage dug at about 22:22 local time.
At least 70 people were taken to hospital, seven of whom underwent surgery, Mayor Claudia Sheinbaum told a news conference, according to the Mexican news service Telediario.
“There are unfortunately children among the dead,” Sheinbaum said. according to the Associated Press.
Filmed of the incident shared on social media showed the moment the ride fell, sending two carriages down on vehicle traffic from both sides.
A survivor who was trapped in a vehicle under the debris was rescued, the mayor said.
Officers have so far identified two of the killers.
Sheinbaum advised members of the public who believed their loved ones might have been involved in reaching out as the effort to identify the victims continued.
“We send our support to all the families who have lost someone and to all those who have someone in the hospital, and we will help them and give them all the support they want,” the mayor said.
Mexico City’s subway system is one of the largest in the world, according to the AP, and the second busiest subway system in North America.
Line 12, also known as the Golden Line, is the most recently launched route and runs through the city from southwest to southeast.
A section of the line was forced to close temporarily in 2014 due to reported infrastructure problems that pose a threat to passenger safety.
Further partial closures were needed in 2017 after a Magnitude 7.1 earthquake that left visible structural damage.
Speaking after Monday’s collapse, the mayor assured the public that there will be an in-depth government investigation focused on what happened, which will include the assistance of international experts.
