England’s World Cup semi-final against Argentina has been classified as the tournament’s highest-risk fixture, prompting heightened security measures involving the FBI, FIFA and local law enforcement.

Officials from the FBI, FIFA and police met on Monday to assess potential security threats surrounding Wednesday night’s clash in Atlanta, with particular attention given to the long-standing rivalry between the two nations and the possibility of tensions spilling over among supporters.

To reduce the risk of clashes, fans from both countries will enter the Mercedes-Benz Stadium through separate gates. However, there will be no segregation once inside the venue, with supporters seated together—a feature that has been common throughout the tournament due in part to the widespread use of ticket resale platforms.

While organisers have made efforts to keep rival fans apart, officials acknowledge there is little they can do once spectators have entered the stadium and taken their seats.

The rivalry between England and Argentina extends beyond football. Earlier this week, Argentina’s foreign minister reiterated the country’s claim over the Falkland Islands, a position that was quickly rejected by British Prime Minister Sir Keir Starmer.
