A gunman has killed a Canadian woman and injured four others at one of Mexico's most popular tourist sites.
It happened at the Teotihuacan pyramids outside Mexico City, with footage showing the man firing from the top of one of the pyramids as people sought cover.
Authorities said two more Canadians were wounded, alongside a Russian and two Colombians, and that the attacker killed himself after Monday's shooting.
Two further people were injured in falls amid the panic and taken to hospital.
Officials also said they found a gun, a knife and ammunition after the shooting.
"What happened today in Teotihuacan pains us deeply," said Mexican President Claudia Sheinbaum on social media.
"I express my deepest sympathy to those affected and their families."
The attacker's identity has not yet been released.

Teotihuacan, built between the first and seventh centuries, is one of Mexico's most popular tourist attractions and had 1.8 million visitors last year.
A tour guide, who spoke on condition of anonymity so as not to put his job at risk, told the Associated Press he was leading a group down one of the pyramids at around 11.30am local time when the gunman began to shoot.
A number of people stumbled in fear and fell down the stairs, he added.
He said he heard between 20 and 30 gunshots ring out before security officials arrived.
Canada's foreign affairs minister, Anita Anand, also expressed her sympathies to those affected by the shooting and said her thoughts were with the family of the woman who was killed.
