Mexico pyramid shooting planned

Investigation into the massacre at the Pyramid of the Moon suggests the gunman, Julio César Jasso, had plotted the attack for two months and carried materials related to the 1999 Columbine shooting.

Eyewitnesses described scenes of terror as the gunman opened fire from the top of the ancient temple, forcing tourists to scramble for safety.

President Claudia Sheinbaum has vowed to beef up security at all major archaeological sites as Mexico prepares to co-host the World Cup this summer.

The incident has raised urgent questions about the safety of international tourists in the country amid a rise in extremist-influenced violence.
