A New York man has been charged with federal hate crimes in three assaults on Jewish protesters at demonstrations over the war in Gaza, according to an indictment released on Wednesday.

The man, Tarek Bazrouk, 20, was arrested at three separate protests in Manhattan over roughly nine months after he kicked and punched Jewish protesters who were wearing religious attire or carrying Israeli flags, federal prosecutors said.

“Despite being arrested after each incident, Bazrouk allegedly remained undeterred and quickly returned to using violence to target Jews in New York City,” Jay Clayton, the interim U.S. attorney for the Southern District of New York, said in a news release on Wednesday.
