All staff and visitors are safe.
Meanwhile, for anyone on the UMass-Boston campus: Steer clear of the library. The same goes for anyone on campus at the other area schools. Here's what Boston University had to say to its students today:
“BUPD working with BPD and are requesting all people to stay clear of Kenmore Sq. and surrounding areas. Please return to your residence and remain indoors. Report any suspicious articles or activity to police.”
Davis also recommended that people in Boston stay home, not congregate among large crowds, and, if staying in a hotel, to return to their rooms.
UPDATE: Now the Boston PD is saying the JFK incident may have been “fire-related.” Regardless, use caution around there.
