One dead, 13 injured at Teotihuacan pyramids in Mexico

(NBC, KYMA) - 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, including six Americans, at the archaeological site north of Mexico's capital.

The shooter was identified as 27-year-old Julio Cesar Jasso of Mexico. He 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 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.

According to Mexican authorities, the youngest person who was injured was six, and the oldest was 61.

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. Central when dozens of tourists were at the top of the pyramid of the moon.

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 posted on social media saying the shooting would be investigated and that she was in touch with the Canadian embassy.
