VIDEO: Gunman shoots several tourists at historic pyramids in Mexico, killing a Canadian

An armed man standing atop one of the historic Teotihuacan pyramids opened fire on tourists Monday, killing one Canadian and leaving at least 13 people injured at the archaeological site north of Mexico's capital, authorities said.

The shooter was identified as 27-year-old Julio Cesar Jasso of Mexico, a state official told the AP on condition of anonymity because he is not authorized to speak about the case. Jasso later died from a self-inflicted gunshot wound, authorities said, and security officials found a gun, a knife and ammunition. Jasso was the sole assailant in the attack, the State of Mexico government confirmed on Monday night.

The local government said seven people were wounded by gunshots. How the other people were injured was not disclosed, but a number of people fell when shooting started, some while climbing on the pyramids.

Those taken to hospitals for treatment were six Americans, three Colombians, one Russian, two Brazilians and one Canadian, the local government said. The youngest person who was injured was 6; the oldest was 61, Mexican authorities said.

Video and photos published by local media showed a man, later identified as Jasso, standing with a gun on top of a pyramid while people ducked for cover. A number of gunshots rang out in the videos.

The Teotihuacan pyramids, a UNESCO World Heritage Site, are a series of massive structures on the outskirts of Mexico City built by three different ancient civilizations. As one of Mexico's most important touristic destinations, the site drew more than 1.8 million international visitors last year, according to government figures.

The shooting took place shortly after 11:30 a.m. when dozens of tourists were at the top of the Pyramid of the Moon. The standing on the structure's platform began firing upward, according to a tour guide who was at the scene and spoke to The Associated Press on condition of anonymity for safety reasons.

"Some people, because they were scared ... threw themselves face down on the ground, and the rest of us started to go down," the guide said, recounting how the shooter, upon seeing the tourists descending the pyramid's steps, began firing.

Another group of visitors lay motionless on the pyramid's platform to avoid being targeted by the shooter, who authorities have not yet identified.

Brenda Lee, of Vancouver, British Columbia, said she was waiting to buy a souvenir when she and others in her group thought they heard firecrackers.

"Before we knew it, someone said, 'No, that's gunfire, run,' and we saw people coming off the top," she told CTV News, one of Canada's national television broadcasters.

"There were thousands of people there and there were a lot of gunshots that just kept coming," Lee said.

The scene quickly turned chaotic as people tried to escape, Lee said.

"And then a fellow jumped," she said. "It was someone trying to get away, and he dropped to the next level, but he fell on his back, and it was ... it just was awful."

In past years, staff at the archaeological site carried out security scans before people entered the area but have since stopped, one local guide noted.

Mexican President Claudia Sheinbaum wrote on social media that the shooting would be investigated and that she was in touch with the Canadian Embassy.

"What happened today in Teotihuacán deeply pains us. I express my most sincere solidarity with the affected individuals and their families," she wrote.

Anita Anand, Canada's foreign affairs minister, said on X that as a "result of a horrific act of gun violence, a Canadian was killed and another wounded in Teotihuacán" and that her "thoughts are with their family and loved ones."

Later in the evening U.S. Ambassador to Mexico Ronald Johnson also expressed "deep concern" and sadness over the deaths and numerous injuries, and said on a post on X that the U.S. is "ready to provide support as needed while Mexican authorities continue their investigation."

The National Institute of Anthropology and History said in a statement that the Teotihuacán archaeological site will remain closed until further notice.
