At least three students are among those injured Monday in the bombings at the Boston Marathon. A Boston University student was critically injured, said a statement from Robert A. Brown, president of the university. He said he couldn't yet identify the student, and that BU police were staying on duty Monday night to provide extra security on the campus. Brown asked all students to remain in their residence halls or homes Monday night. Tufts University announced that two students who had been watching the marathon "sustained non-life-threatening injuries and are being treated at area hospitals." And the University of Massachusetts at Boston closed Monday night as a "precautionary measure" because of investigations of a possible incendiary device at the John F. Kennedy Library and Museum, which is at one end of the university's campus.
Many colleges have groups of runners in the marathon and were issuing press releases Monday night reassuring friends and family members that their students were safe.
