Unconfirmed Reports Of Explosives In Four Harvard Buildings Prompt Evacuation

Update: some additional information on what the "motivation" behind the bomb scares may have been from The Wire [4]:

Following unconfirmed reports of explosives at four central buildings on the Harvard University campus, the school was forced to cancel Monday morning's exams. The bomb threat led to the evacuation of the Science Center, Thayer, Sever and Emerson Halls "out of an abundance of caution," Harvard said in a statement. While it's not clear what, exactly, prompted the evacuation, the not-conidential timing of the threat will give some nervous a reprieve:

The bomb scare has moved to the Ivies. Just out from the Harvard twitter account:

Alert: Unconfirmed reports of explosives at four sites on campus: Science Center, Thayer, Sever, and Emerson. Evacuate those buildings now.
