Pro-Palestinian demonstrators targeted in apparent stink bomb attack at Columbia University

Demonstrators at Columbia University say they were attacked with a stink bomb during a gathering in support of Palestinians amid the ongoing Israel-Hamas war.

A group of demonstrators at Columbia University say they were attacked with a stink bomb during a gathering in support of Palestinians amid the ongoing Israel-Hamas war.

The New York Police Department told ABC News there is a report on file for assault after the protesters said they smelled a foul odor and began to feel nauseous, accompanied by headaches, during a protest Friday. The victims refused medical attention at the scene, according to the NYPD.

No arrests have been made and the investigation remains ongoing, officials said.

The university's Department of Public Safety is also investigating incidents in collaboration with local and federal authorities after several reports were filed in connection with Friday’s protest "that are of great concern," according to a Columbia University spokesperson.

"While the investigation is proceeding, we continue to seek the university community’s support. Reporting is essential so that the proper authorities -- including the NYPD -- can track down the facts and take action as necessary," the Columbia University department said Sunday.
