A Canadian woman was killed after a man opened fire from a famous pyramid in Mexico on Monday, according to authorities. 
The unidentified victim was fatally shot by an unknown man in the Teotihuacán archaeological zone, just about an hour outside of Mexico City, the Mexican government said. 
The shooter took his own life after allegedly killing the tourist. 
At least six people were injured - four by firearm and two by falling, the State of Mexico said. 
They are receiving medical treatment. 
Among the people wounded is one Canadian, a person from Russia, and two Colombian nationals, the Secretary of Security for the State of Mexico, Cristóbal Castañeda, said, CTV News reported. 
Chilling footage circulating on social media showed the gunman firing a gun from halfway up the Pyramid of the Moon while terrified tourists took cover behind the stairs below. 
Following the horrific incident, Mexican President Claudia Sheinbaum said: 'What happened today in Teotihuacan hurts us deeply. 
I express my sincerest solidarity to the people affected and their families.' 
Sheinbaum said that federal and state security forces were being sent out to the site to investigate, and that her administration is in contact with the Canadian government. 
An unidentified man opened fire while on a famous pyramid at the Teotihuacán archaeological zone on Monday in Mexico 
At least six people were injured - four by firearm and two by falling, the State of Mexico said 
The Teotihuacán pyramids are a popular tourist attraction that people from all over the world flock to so they can take in the archeological sites. 
Tim Chung, an American tourist who was visiting Mexico from Seattle, told NBC News he was there with a tour group when shots rang out. 
'All of a sudden I see a guy fall off one of the viewing platforms and then I heard a shot and another person fall off and then I knew something bad was happening and heard screams,' Chung told the outlet. 
Police officers are seen at the Teotihuacan archaeological zone following the deadly shooting 
He described the incident as 'unbelievably sad,' and that everyone in the group, including him, were thankfully unharmed. 
Teotihuacán, a pre-Hispanic city, was one of the most significant cultural centers in Mesoamerica. 
It welcomes 1.8 million tourists every year.
