Boston Library Fire May Be Unrelated to Bombs

It looks like a fire that broke out at Boston's JFK presidential library this afternoon might be a coincidence, not a third attack, reports the Boston Irish Reporter. Library officials say that the fire broke out in the mechanical room of the building's new wing and that everybody is safe, reports the Washington Post. "Any tie to Boston Marathon explosions is pure speculation," says a library statement. Boston Police Chief Ed Davis initially said authorities were treating the incident as related to the marathon attacks, but the department later tweeted that reports linking them "could be premature."

In his press conference, Davis urged Bostonians to stay inside, and asked visitors to return to their hotels. If people do go outside, he asked them not to congregate in large groups. Other developments out of Boston:

Various news outlets reported earlier that police asked providers to shut down service to guard against the remote detonation of bombs. Verizon and Sprint say they got no such requests.
