Sept. 11 (UPI) — At least three people are dead and 90 are injured following the explosion of a gas tanker in Mexico City, officials said.

Mexico City Mayor Clara Brugada Molina announced the casualty toll online, listing all 90 people who were injured and the hospitals where they were being treated. Ages of the victims ranged from 6 months to 60 years old.

At least 10 people have been discharged from the hospital, she said.

Earlier, before any fatalities had been reported and when only 57 people were known to be injured, she said 19 were listed in serious condition.

The tanker exploded under Concordia Bridge, resulting in a fire.

“The roadways remain closed to traffic and there are disruptions in public transportation of the area,” she said on X, while posting pictures showing victims being loaded onto police helicopters and the smoking wreckage of the tanker.

President Claudia Sheinbaum Pardo of Mexico expressed her “solidarity and support” to the families of the three deceased victims and to those of the injured.

“Likewise, I express my recognition to the emergency services that are supporting in this unfortunate incident,” she said in a statement, adding federal agencies were responding to the explosion.
