CAMBRIDGE, Mass. (December 16, 2013) Four buildings on the Harvard University campus outside Boston were evacuated Monday because of unconfirmed reports of explosives.
The school tweeted that there have been no reports of any explosions.
Three of the buildings in Cambridge border Harvard Yard.
The school posted alerts on its emergency page and its Twitter account that said both school and city police are investigating, and the university will provide more information soon.
Harvard said in a statement that its university police department received the unconfirmed report that explosives may have been placed in the four buildings and they were evacuated out of an abundance of caution.
Two of the buildings were cleared late Monday morning.
Students were told they could return to Thayer Hall, which is a dorm, and Emerson Hall, a classroom building.
The two other buildings, the Science Center and another classroom building, remained closed until Monday afternoon.
A search turned up no evidence of explosives.
Final exams are underway at the Ivy League school.
