Columbia University says it is boosting security after an incident on campus involving protesters. Earlier this week, the university said in a statement a class on "The History of Modern Israel" was disrupted Tuesday by a group of students who handed out fliers showing violent imagery.

These people are openly against not just discussion, they’re openly against anyone in the university learning about the history of Israel,” one student told The Post.

Anti-Israel protesters donned in keffiyahs invaded an Israeli studies class and distributed hateful propaganda to the students reminiscent of Nazi propaganda.

Fox News national correspondent Bryan Llenas reports on new anti-Israel protests at Columbia University on ‘The Story.’

Palestinian protesters of an Israeli history class on January 21.“No group of students has a right to disrupt another group of students in a Columbia classroom,” a statement from Interim President Katrina Armstrong said.
