“The bomb scare at Harvard University today was triggered by an e-mail warning that explosives had been planted in four buildings at the heart of the storied campus, according to a law enforcement official.

“At 2:44 p.m., the university announced that the Science Center, the last of the four buildings, had been deemed safe.

“Law enforcement officials had already combed through and cleared Thayer Hall, a freshman dorm, and Sever and Emerson halls, two buildings that contain lecture halls.

“…According to the school’s academic calendar, final exams are scheduled for this week for undergraduates.

“College officials said they were working to identify and reschedule exams that were disrupted by evacuations of the buildings.

“Officials also planned to make an announcement about the impact on afternoon exams as soon as possible, a university spokesman said in an e-mail.” – Yt
