This morning, four of Harvard University's buildings were evacuated after the university received unconfirmed reports of explosives had been placed inside of them

Both the Harvard University Police Department and the Cambridge Police Department were on the scene to investigate, and campus police ordered students and faculty to exit the Science Center, Server, Thayer and Emerson Halls

According to the Wall Street Journal, Harvard has asked the Massachusetts State Police to send its bomb squad and bomb dogs. Officials also add that the FBI is responding to the incident. At 10:40 p.m., the university released its most recent update on the situation:

As you learned from the MessageMe alerts this morning, the Harvard University Police Department (HUPD) received an unconfirmed report that explosives may have been placed in four buildings on campus: the Science Center, and Thayer, Sever and Emerson halls. Out of an abundance of caution, the buildings have been evacuated while the report is investigated by the HUPD and the Cambridge Police Department. [The investigation is ongoing.]

Access to Harvard Yard has been restricted to residents of the Yard with Harvard ID. As of the writing of this message the report remains unconfirmed and the HUPD has no reason to believe there is a threat to any other site on campus.

Harvard's focus is on the safety of our students, faculty and staff. We will continue to update the community via MessageME and through messages posted here and on the University's Twitter and Facebook accounts.

We will update with more information as it becomes available.
