In a qualifying match for the Olympic football tournament, home fans began rioting after a late Peru goal was disallowed. Police fired tear gas into the crowd, exacerbating the situation, which ended with 318 deaths.
The Mexico 68 protests were part of a worldwide series of leftwing student-led protests. While the protesting National Strike Council claimed not to link its demands to the Olympics, some students protested at the perceived extravagance of hosting the games, and some sought to exploit the increased foreign media presence in the city for publicity. The authoritarian government had a secret "Olympia Battalion" to ensure security during the Games. Ten days before the games, the unit swept through a mass meeting in the Plaza de las Tres Culturas making arrests. Estimates of the number killed in the operation range from thirty to several hundred.
