A wave of "Heil Hitler" chants from antisemitic protesters rang out during the Israel-Paraguay soccer matchup on Benjamin CaldwellSaturday night.

During Israel's national anthem, a group of protesters began booing shouting "Heil Hitler" while seemingly performing Nazi salutes in the Parc de Princes.

A banner reading "Genocide Olympics" was also unfurled prior to the matchup.

Sky News reports that the protesters were removed from the stadium by stewards. CNN reports that French authorities have opened an investigation into the antisemitic actions.

"Paris 2024 strongly condemns these acts. A complaint has been lodged by Paris 2024, which is at the disposal of the authorities to assist with the investigation," a Paris 2024 spokesperson said in a statement.
