Mexico City — A massive explosion rocked the capital city of Mexico City Tuesday morning, killing at least five people and injuring dozens more, officials said.
The blasts were reported at 6:40 a.m. local time and were believed to have been caused by a gas leak from a storage facility, the country’s Civil Protection and Security Agency said in a statement.
The agency did not provide details on how the blast occurred, citing safety concerns.
Mexico City Mayor Miguel Angel Osorio Chong said the blast was a “terrorist attack” but said the agency would investigate.
The explosion occurred at the storage facility where gas was stored and exploded, according to a statement by the Civil Protection Agency.
The blast took place on the corner of the National Palace, a major tourist destination, and the Plaza de la Revolución, where thousands of tourists are expected to gather for the World Cup.
A fire broke out at the site, which was not immediately clear.
The Civil Protection agency said authorities were still trying to determine the cause of the explosion.
A bomb squad was brought in to extinguish the flames, while police closed off streets surrounding the site.
It was not clear whether the explosion was related to a bomb.
There were no immediate reports of casualties, but many were treated for shock and burn injuries.
The site was evacuated by the military, with about 400,000 people evacuated by taxi from the streets around the National Arena, where the World Cups are being held.
The World Cup will be held at the venue, which is located on the top of a mountain overlooking the capital, the capital’s mayor said in February.
