Harvard University said on its website on Monday that it had received an "unconfirmed" bomb threat and was evacuating four buildings on its campus outside Boston.
Three classroom buildings - The Science Center, Sever and Emerson Halls - and one dormitory, Thayer Hall, were affected, the Ivy League school said on its website.
The threat comes three days after a coordinated attack by gunmen and suicide bombers killed 127 people in Paris.
