Climate activist Greta Thunberg has been labeled "antisemite of the Week" by the Jewish watchdog group StopAntisemitism following her arrest at an anti-Israel rally. The group criticized Thunberg for aligning with protesters who oppose Israel, accusing her of turning her activism into a platform for anti-Semitism, the New York Post reported.

"She has sadly transformed her activism into a platform for vile Jew-hatred," the organization said.

Thunberg, 21, was arrested on September 4 while demonstrating with Students Against the Occupation, who called on Copenhagen University to cut ties with Israel, including climate change programs. StopAntisemitism founder Liora Rez condemned Thunberg, accusing her of prioritizing hatred for Israel over environmental activism despite Israel's efforts on climate action.
