Protesters and police clash outside Mexico City’s Estadio Azteca on Thursday as the 2026 FIFA World Cup opening match gets underway. Multiple outlets report that riot police are involved and that the violence occurs just before or around the start of the tournament opener, with demonstrators gathering near the stadium. Accounts describe confrontations that disrupt the area around the venue and create security concerns on opening day.

While the match itself is covered as proceeding as scheduled, with Mexico playing South Africa in Mexico City, several reports emphasize that the unrest is separate from the on-field event. One outlet also mentions an additional incident involving a reported medical emergency during the day.

Authorities and media accounts indicate that order is eventually restored despite the clashes. Overall, sources agree on the timing (opening day), location (Azteca/Estadio Azteca in Mexico City), participants (protesters and police/riot police), and that the World Cup match between Mexico and South Africa continues even as violence unfolds outside the stadium.
