Harvard University and the streets around it are back open after several buildings on the Cambridge, Massachusetts, campus were evacuated Monday morning due to "unconfirmed reports" that explosives may have been placed there.
Those four buildings were the Science Center, Thayer, Sever and Emerson Halls. The university emphasized on Twitter and on its website that there were no reports of explosions.
"Out of an abundance of caution, the buildings have been evacuated while the report is investigated," the university said Monday morning on the emergency section of its website. "Harvard's focus is on the safety of our students, faculty and staff."
The "explosives threat" was sent to Harvard police via an e-mail sent from an internet cafe, according to an intelligence source briefed on the investigation.
Two law enforcement sources told HLN they treated the situation like a threat but believed it was a hoax. A law enforcement official told HLN the FBI responded as a precaution. Officials said final exams, which began last week and are scheduled to go until Friday, have been canceled for Monday.
Thayer Hall is a freshman dormitory while the Harvard Science Center and Sever and Emerson halls are academic buildings.
