Sections of Egyptian and Cape Verdean fans have accused their Argentinian counterparts of violent behavior during the reigning champions' last two World Cup matches. The accusations, coupled with at least one high-profile allegation of racism, have brought new scrutiny to Argentina's title defense.

On Tuesday, Egypt led Argentina 2-0 in Atlanta before Messi's side staged a stunning late comeback to advance to the quarterfinals. Argentinian fans reacted to the team's poor start and eventual turnaround by attacking Egyptian supporters, throwing beer at them, as captured on video. After the match, Argentinian fans also waved the Israeli flag towards the Egyptian coaching staff.

Egypt's head coach Hossam Hassan has spoken passionately about the plight of the Palestinian people, raising the Palestinian flag after Egypt's win over Australia last week.

In a previous match, Cape Verde fans told Al Jazeera that Argentinian supporters threw beer bottles at them after every goal scored by the African side. The Cape Verde fans noted they were outnumbered and targeted.

FIFA has not responded to requests for comment on the incidents but issued a statement condemning abuse hurled at streamer IShowSpeed, launching an investigation. FIFA called the World Cup "a celebration of unity, diversity, and respect."
