What’s happening at the World Cup one day before tournament starts?

The FIFA World Cup is set to begin in Mexico City's Estadio Azteca with Mexico hosting South Africa. The tournament has already been marred by controversy, with the Iranian football federation accusing the US of revoking its allocation of tickets for Iran's group games, citing bureaucratic hurdles and visa issues. Protests are also taking place in Mexico City, with demonstrators from the country's teachers' union threatening to shut down roads around the venue before the opening game.
