BBC is reporting that there's a bomb threat at Harvard.
Harvard University in the US state of Massachusetts has evacuated its campus amid "unconfirmed reports" of explosives at four of its buildings.
The university's Twitter feed said there were no reports of an explosion and no indication that any bombs had been placed on campus.
Harvard campus police and local police were said to be on the scene investigating.
The alert comes as final exams are under way at the elite college.
It said in a statement: "The Harvard University Police Department this morning received an unconfirmed report that explosives may have been placed in four buildings on campus: the Science Center, Thayer, Sever and Emerson Halls."
The campus was being cleared "out of an abundance of caution", added the statement.
