Belgium has summoned the United States ambassador following remarks he made on social media accusing the country of engaging in antisemitic prosecution, Foreign Minister Maxime Prévot said Tuesday, in a rare diplomatic rebuke between close allies.

The dispute stems from comments by U.S. Ambassador Bill White, who criticized Belgian authorities over an investigation involving members of Antwerp’s Jewish community. White described the probe as “unacceptable harassment of the Jewish community here in Antwerp and in Belgium” in a post on X.

In response, Prévot rejected the accusation, calling it “dangerous disinformation.”

“Labeling Belgium as antisemitic is not just wrong, it’s dangerous disinformation that undermines the real fight against hatred,” Prévot wrote Monday on X. He added that ambassadors accredited to Belgium are expected to respect the country’s institutions and judicial independence.

“An ambassador accredited to Belgium has a responsibility to respect our institutions, our elected representatives, and the independence of our judicial system,” Prévot said. “Personal attacks against a Belgian minister and interference in judicial matters violate basic diplomatic norms.”

According to national broadcaster VRT, Belgian authorities are investigating whether three men in Antwerp conducted circumcisions without certified medical training. The probe has drawn scrutiny in the city, which is home to one of Europe’s largest Orthodox Jewish communities.

White said he planned to visit the three accused men in Antwerp and invited Belgium’s health minister to join him.

The Belgian Foreign Ministry did not immediately comment on the outcome of the summons.
