Boston Police etc. are warning people away from Norfolk St. in Cambridge, maybe a block or two from where I used to live in Cambridge.  It may be where they're detonating a bomb, maybe something else.  A dangerous situation they're saying. 

Now they're reporting that these brothers have been in the U.S. for more than 10 years, since they were children.  Though they were born in Russia, it seems they grew up here.  I'd thought before that if they lived in Cambridge and weren't well to do, they might live in the area near where I lived, East Cambridge, and that's where Norfolk St. basically is.
