In Amsterdam, police detained dozens of pro-Palestinian demonstrators on Sunday after they defied a ban on public protests in the city. Hundreds gathered in Dam Square, calling for an end to the conflict in Gaza and voicing opposition to the protest ban.

The ban on demonstrations was implemented by Amsterdam’s Mayor Femke Halsema after a series of “hit-and-run” attacks targeted Israeli football fans on Thursday night following a match between Maccabi Tel Aviv and Ajax Amsterdam. The Israeli government has since advised citizens to avoid Israeli cultural and sports events abroad, specifically warning against attending the upcoming France-Israel football match in Paris.

Thursday’s attacks in Amsterdam, which left five people hospitalized, were reportedly driven by antisemitism as Israeli fans were targeted throughout the city. Leaders in Europe, the U.S., and Israel condemned the violence, which took place just before the anniversary of Kristallnacht, the 1938 Nazi pogrom against German Jews.

Amsterdam police noted disturbances the night before the match as well, including incidents of Israeli supporters burning a Palestinian flag and assaulting a taxi. Police chief Peter Holla confirmed incidents “on both sides.”

In response, Mayor Halsema declared Amsterdam a “high-risk security area” and imposed a ban on public assembly through the weekend. Despite this, Sunday’s demonstrators argued for their right to protest Israel’s actions in Gaza and the behavior of Maccabi supporters.
