Atlanta police said additional personnel and resources are already in place and will continue to be strategically assigned in and around event venues for Wednesday's match. The matchup is considered one of the tournament's highest-risk games because of longstanding tensions between the two nations stemming from the 1982 Falklands War.
Videos circulating online appear to show England and Argentina fans clashing in Miami, where England played Norway over the weekend. Argentina is the defending champion, while England has not won a World Cup since 1966. It is the first time since 1966 that England's national team has earned a berth in the semifinals.
Argentina has claimed three World Cup titles and has been the tournament's runner-up twice. The winner of Wednesday's semifinal will face Spain in the final on Sunday in East Rutherford, New Jersey.
