HARVARD UNIVERSITY HAS evacuated a number of its buildings after receiving what it’s called ”an unconfirmed bomb threat”.

Four buildings have been evacuated and are now being searched by police officers who are now at the scene. An exclusion zone is in place and access has been restricted.

It is believed that the search will take at least a number of hours.

Harvard’s executive vice president Katie Lapp wrote in an email to students, staff and faculty members this afternoon that the bomb threat was made in an email.

“As of this writing, nothing to substantiate the emailed threat has been found. Harvard is working with local and federal law enforcement officials to investigate the source of the threat, which has not yet been determined,” the email read.

It went on to reference the “recent tragic events in locations ranging from Paris to Beirut” and said that the safety of members of the was their “top priority”.

Lapp concluded by saying that they would keep people updated about how the threat develops.
