A Mexico City metro viaduct collapsed on the night of May 3, sending a train plunging into a road, trapping cars under rubble and killing at least 13 people, authorities said.

Mexico City’s civil protection agency tweeted that nearly 70 people were injured in the crash in the south of the capital and taken to nearby hospitals.

“A support beam gave way,” said Mexico City mayor Claudia Sheinbaum, who rushed to the scene of the crash, which occurred around 10:30 p.m. local time.

The video showed at least one broken train with dozens of rescuers digging through the rubble of the collapsed viaduct. Cars could be seen trapped below.

The accident occurred on metro line 12, the construction of which was marred by complaints and accusations of irregularities.

“What happened in the metro today is a terrible tragedy,” Mexican Foreign Minister Marcelo Ebrard tweeted.
