Mexico tightens security at Teotihuacan following fatal attack

The archaeological site of Teotihuacan in Mexico has reopened to the public after an armed attack last Monday, when a man killed a Canadian tourist and injured 13 others before taking his own life.

Julio César Jasso Ramírez, 27, opened fire on visitors, reportedly influenced by previous mass shootings that gained global attention, such as the Columbine High School massacre, which took place in the United States on April 20, 1999, CE Report quotes ANSA.

The site has now been placed under reinforced security measures, two months before the start of the 2026 FIFA World Cup, which Mexico is co-hosting with the United States and Canada.

The attacker is believed to have acted alone and reportedly suffered from “psychological issues.” Between January and July 2025, Teotihuacan was the second most visited archaeological site in the country, with nearly one million tourists.
