Bomb threats toward six historically black colleges and universities (HBCUs) disrupted campus operations Monday.
CNN reports the universities who received the threats were: Southern University and A&M College, Howard University, Bethune-Cookman University, Albany State University, Bowie State University and Delaware State University, according to campus spokespeople.
It's the second time this month that several HBCUs received bomb threats on the same day. The threats in some cases have led schools to relocate students, faculty and staff while searches were performed. On Jan. 5, at least three HBCUs, including Howard University, received bomb threats. Nothing was found on any of the campuses that received threats, university officials said.
Classes at Southern University were canceled, and students were told to remain in their residence hall rooms until an all-clear was issued.
A Washington Metropolitan Police Department spokesperson confirmed that at Howard University the "scene has been cleared with no hazardous materials found."
The FBI is working with local law enforcement to address potential threats, reports ABC News Go.
