Harvard, UMass Order Evacautions

On Monday morning, just after 9 a.m., Harvard University issued an alert that the college had received "unconfirmed reports" of undetonated explosives in four of the campus' buildings. It ordered mandatory evacuation of those four buildings: Science Center, Thayer, Sever, and Emerson. By 9.30 a.m., Harvard and Cambridge police were on the scene. There have been no reports of detonation, nor has the report been confirmed by either the college or authorities.

And at noon, across the city at the University of Massachusetts, the college issued an alert about a possible gunman on campus. The McCormack building was evacuated, and officials are on scene. Minutes later, Boston police Tweeted: "There were reports of a threat at @UmassBoston. There is no threat. False report. Scene is clear."

By 3 p.m., Harvard had also also re-opened its buildings and deemed the area safe.

On Harvard's "Alert" page on its website, the university had posted:

Saturday marked the one-year anniversary of the Sandy Hook shooting in Newtown, Conn., in which 20 schoolchildren and six of their teachers were killed by Adam Lanza.

The news follows the fatal shooting at Colorado's Arapahoe High School on Friday afternoon. The gunman, Karl Pierson, shot fellow student Claire Davis, apparently at random, before committing suicide by shooting himself. Davis remains in critical condition at a nearby hospital. It's reported that Pierson had intended to shoot a teacher at the school.
