Thunberg “has joined the ranks of keffiyeh-clad protesters, brazenly voicing her disdain for the Jewish state,” the watchdog group StopAntisemitism said Friday, days after Thunberg was among those hauled off by Danish police during a demonstration at Copenhagen University.

“She has sadly transformed her activism into a platform for vile Jew-hatred,” the organization added.

The 21-year-old was arrested on Sept. 4 while protesting with the group Students Against the Occupation, which called on the university to cease all connections with Israel, including putting an end to several cross-university student programs.
