The New York Times has a graphic showing the locations of the two explosions, about a block apart on Boylston St.
An official tells the AP that additional devices were located, in addition to the two that exploded. It's not known if this includes the one detonated by the bomb squad.
Possibly related, at 4:27 the scanner reported a confirmed explosion at the JFK library, with no injuries reported.

An official tells the AP that cell phone service in downtown Boston has been shut off or limited to prevent detonations of any undiscovered devices. (Update: this was apparently a false report.)

From the AP, a spectator tries to find a friend after the marathon was canceled:
Via Eric Twardzik, a photo taken around 5:30 of a man being handcuffed on the Boston Common. Twardzik says he's wearing a white baseball cap:
In a 6:00 press conference, the police commissioner says the fire at the JFK library appears to be unrelated to the marathon blasts.
The Post has been reporting that a potential suspect is under guard at a Boston hospital, citing "federal officials." Police Commissioner Davis seemed to dismiss that, saying BPD had no one in custody. NBC News now reports on a "possible suspect" who was injured in the blast. It's worth noting that neither the Post nor NBC had claimed anyone was arrested.
