The leader of a pro-Palestinian group in the Netherlands called one of the country’s main Jewish groups a “pro-occupation lobby.”

Jan Keulen, director of The Rights Forum — a group that was founded by former prime minister Dries van Agt, made the allegation on Saturday in reaction to a police complaint in which the Central Jewish Board, or CJO, and another group accused The Rights Forum of consistently allowing antisemitic rhetoric on its Facebook page.

In a statement Saturday, Keulen dismissed the May 10 complaint as a “political smear campaign” by CJO and the CIJO youth and young adult division of the Centre for Information and Documentation on Israel (CIDI), a watchdog on antisemitism.

The complaint details dozens of antisemitic comments by at least a dozen users whose texts were not removed for months and years even though they violate Dutch law. Some of these comments were removed following the complaint, while others remain.

Noting the Central Jewish Board and CIDI anti-Semitism watchdog calls in the past for the Netherlands to adopt the International Holocaust Remembrance Alliance’s definition for antisemitism, Keulen argued that the “cat is out of the bag” showing the Jewish groups to be “a pro-occupation lobby that will not rest until the definition of antisemitism is stretched and politicised.”

The two groups did not reference the definition in their complaint to police. CIDI favours territorial concessions by Israel to avoid it controlling Palestinian populations or land, which it says should be part of a Palestinian state. CJO considers this issue beyond its purview.
