Jewish students at Cardiff University say they feel "unsafe walking between lectures".
Cardiff Jewish Society said members were "intimidated, abused and harassed" when they wanted to speak on a motion at the student union Annual General Meeting last week.
The motion called on the student body to vote for an immediate ceasefire in Gaza.
But one of the motion's resolutions was to organise educational resources on "how to spot lies and propaganda from the state of Israel".
In a statement, the society said members were "left shaking in their seats" and "two Jewish students had panic attacks".
The spokesperson for the society said members now "fear for their security on campus" and that they "just want to be able to do the things that all other students do".
