NBC reports:

"Boston police say there was no specific intelligence warning of any kind of attack, and federal officials tonight say there is no reason to think that this is part of any larger threat. At this point they believe it is confined to Boston, but a meeting tonight will decide whether any kind of national alert will be sent out. There is no suspect in custody, authorities say, but some people are being questioned, including some with injuries who were taken to Boston hospitals. One of those, a person in whom there is some interest, is a young person who was here on a student visa," NBC reports.
