The second World Cup semifinal, held on July 16 Beijing time, saw the reigning champions Argentina overturn a deficit to defeat England 2-1, securing their place in the final for a second straight tournament.

Following the game, Argentine players engaged in a provocative act on the field. They unfurled a white-and-black banner declaring "The Malvinas Islands (Falklands) belong to Argentina."

This has sparked strong reactions from the British media, with The Athletic contacting FIFA for comment. As is well known, FIFA's stadium regulations prohibit "banners, flags, flyers, clothing, and other items that are political, offensive, and/or discriminatory." Players and their teams found in violation may face disciplinary action from the tournament organizers, their national football association, or FIFA itself.

The Argentine players' actions clearly constitute a serious violation. Doing so in a globally watched World Cup semifinal is particularly controversial, and they are likely to face a heavy penalty from FIFA.
The Malvinas Islands (known as the Falkland Islands in English) are located in the South Atlantic Ocean. Britain occupied them in 1833 and has maintained control ever since, but Argentina has consistently claimed sovereignty over the territory.
Argentina lost the 1982 Falklands War, after which Britain resumed administrative control. To this day, Argentina has not relinquished its claim, while Britain maintains de facto authority based on the principle of self-determination of the islanders, leaving the sovereignty dispute unresolved.

Due to the Falklands/Malvinas dispute, matches between the England and Argentina men's national football teams in the World Cup have always been intensely charged with hostility.
