Days after the deadly terror attacks in Paris, Harvard University has received a bomb threat following which several buildings have been evacuated.
"An unconfirmed bomb threat has been received. The Science Ctr, Sever, Emerson, and Thayer Halls are being evacuated," the university's official website said.
The buildings have been evacuated and law enforcement officials are on scene. Entry to the Yard is restricted.
The four buildings are being searched. The process is likely to take several hours.
