A display created by pro-Israel students at Tulane University to raise awareness for 136 Hamas victims was interrupted by an individual who wrote “FREE PALESTINE” in chalk on the ground.

Students Supporting Israel Tulane (SSI Tulane) hosted the event on Jan. 18 on campus in New Orleans, Louisiana during which the perpetrator was captured on video wearing a mask and has since yet to be identified.

The SSI Tulane table was also set up to celebrate the birthday of one of the youngest hostages, Kfir Bibas, who would have turned one year old on the date of the event.

Following the incident, the university put out a statement, reminding students that chalking is not allowed on campus. In an email to all students, Vice President of the Division of Student Affairs Dusty Porter wrote: “The university has been and will continue to remove all chalking across campus, regardless of content, through at least the end of the spring semester as we consider our current chalking policy.”
