Columbia University says it identified two individuals from an “affiliated institution” who took part in disruption of course on the history of modern Israel last week. The students have been barred from entering the campus and referred to their “home institution for further investigation and discipline.

The Ivy League university, an epicenter for protests last year, says it has suspended one student after “expediting” its investigation into a group who disrupted a class on Israeli history.

We're keeping our eyes on it >> These protest participants were not Columbia students but were reportedly enrolled at an affiliated academic institution. The Public Affairs office said that they had been barred from the campus and referred to their home institution for investigation and discipline.

NEW YORK -- 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.

Some of the flyers were quickly crumpled up by students as one peer in the class said, “We don’t want your sh-t.”

The proposal was leaked this week by an anti-Israel student group but was confirmed by the resolution’s author.
