The renowned archaeological site welcomed visitors once again under the protection of nearly 300 security personnel, police officers, and National Guard members. A 27-year-old Mexican gunman opened fire on tourists at the complex on Monday, killing a Canadian woman and injuring thirteen others, including a 55-year-old Dutch woman, before taking his own life during an exchange with police. The reopening comes just days after the incident, though visitor numbers remained limited as authorities maintained strict security measures at the UNESCO World Heritage site.
