Mexico City World Cup Stadium became the center of two very different scenes on Thursday as the 2026 FIFA World Cup officially began. While fans inside the famous stadium celebrated the start of football’s biggest event, violent clashes broke out outside the venue shortly before kickoff. Protesters attempted to move toward the stadium gates and were met by riot police, leading to a tense confrontation that included tear gas, rocks, and damaged property. At the same time, a separate medical emergency unfolded when a man reportedly suffered a heart attack while heading to the match. The incidents happened just minutes before Mexico and South Africa kicked off the tournament opener. According to reports from the Daily Mail and videos shared online, security forces quickly responded as authorities tried to prevent the unrest from spreading around the stadium.
Protesters and riot police clash outside Mexico City Stadium
About 10 minutes before the opening match began, hundreds of protesters approached the northeast side of the stadium and attempted to enter the inner security area. According to the Daily Mail, some protesters threw rocks and flares at police officers. A truck parked near the venue was also damaged during the unrest.
Riot police moved in from Gate C and pushed the crowd back. Officers used tear gas as they worked to clear the area and prevent protesters from reaching the stadium entrances.
Planned demonstrations coincide with World Cup opener
Reports before the match said several demonstrations had been planned across Mexico City to coincide with the World Cup opening day. Groups expected to participate included families of missing persons linked to Mexico’s drug war, members of the CNTE teachers’ union, judiciary workers, transport employees, healthcare workers, and farming organizations.
Because of those plans, police had already increased security around the stadium and nearby streets.
Medical emergency reported near stadium entrance
Away from the clashes, another serious incident was reported outside the venue. Videos shared online appeared to show a man receiving CPR from medics after suffering a suspected heart attack while making his way into the stadium.
Officials had not released an update on his condition at the time of reporting.
Heavy security remains as World Cup begins
After the initial unrest was brought under control, large lines of riot police remained stationed around the stadium gates. An additional security perimeter was also established.
The Daily Mail reported seeing a policewoman with a head injury being taken away for treatment. Meanwhile, inside the stadium, fans watched the opening ceremony featuring Shakira before Mexico made a fast start in the tournament opener against South Africa.
