The United States Federal Bureau of Investigation has classified Wednesday’s FIFA World Cup semi-final between England and Argentina as the tournament’s highest-risk fixture.

According to the Daily Mirror, the assessment followed a security meeting on Monday involving the FBI, FIFA officials, and local law enforcement.

During the meeting, the media platform reported on Tuesday that the FBI labelled the match the “highest-risk” one over concerns of the long-standing rivalry between the two nations and the potential for crowd disturbances.

As part of the security arrangements, England and Argentina supporters will enter the Mercedes-Benz Stadium through separate gates, although there will be no segregation inside the venue.
