There were campus emergencies on both sides of the Charles River on Monday, with Harvard evacuating students from four halls a little after 9 a.m. and locking down Harvard Yard because of unconfirmed e-mailed reports of explosives in each and the University of Massachusetts at Boston evacuating a building after reports of a person wielding a gun.

By 11 a.m., searches had found no explosives in the Science Center or Thayer, Sever or Emerson halls at Harvard, and students who remained evacuated were wondering when their missed final exams would be made up, according to reports in The Harvard Crimson.
By 12:56 p.m.,ย Thayer and Emerson Hall were cleared for returning studentsย and some were grumbling about the scare being the result of a student unprepared for a test. (When final exams were canceled, some students โerupt in applause,โ the Crimson tweeted.) The final clearances came at about 2:45 p.m. But after recent terrorism and random school assaults, officials could not take chances.ย Harvardโs official statement:
Out of an abundance of caution, the buildings have been evacuated while the report is investigated. Harvardโs focus is on the safety of our students, faculty and staff. We will update the media when we have more information.
Cambridge Public Schools responded as well, with the nearbyย Baldwin School and Cambridge Rindge & Latin School โplaced in a secure and hold mode as a precaution,โ officials said, meaning recess was to be held indoors at the Baldwin and lunch is on campus at the high school. โAlso. no unknown individuals are allowed into the buildings and all doors remained locked,โ officials said. โAll other activities within the school continue.โ
The alarm in Boston went out shortly afterward, with UMass Boston tweeting at 11:55 a.m. to alert its community that they were to evacuate its McCormack Building while law enforcement gathered to deal with a โpossible person with a firearm.โ At 12:27 p.m., the report was cleared, with State Police calling it a โfalse threatโ but clarifying that the four Harvard buildings remained evacuated while the search for possibly explosives went on.
When the situation at Harvard remained unresolved at 12:15 p.m., the Crimson tweeted that the Department of Homeland Security had joined State Police and the Harvard and Cambridge police departments at the Harvard Square campus โas threats of explosives remain unconfirmed.โ
When shortly after noon the Harvard Square Business Association incongruously sent out a peaceful image of the square at dusk with the label โIt’s beginning to look a lot like Christmas!,โ resident Saul Tannenbaum responded on Twitter: โExcept for the bomb squads and SWAT teams, sure.โ
Update on Dec. 17, 2013: Harvard sophomore Eldo Kim, 20, is accused of sending โseveralโ e-mailed bomb threats to avoid taking a final exam, trying to hide his identity by using the Internet router Tor. The FBI affidavit is here, via CBS News.
