Obama Speech LIVE: Watch President Address Nation After Boston Marathon Bombings

President Obama will be addressing the nation at 6:10 p.m. EDT following today's attack on the Boston Marathon. A live stream will be added to this post when that information becomes available.

Here's a quick rundown of what we known so far:

- Two bombs were confirmed detonated at the Boston Marathon. Other explosive devices may have been found and disposed of by police at Boston's Mandarin Oriental Hotel, or they have merely been suspicious containers which were destroyed to eliminate the risk of a secondary blast.

- A simultaneous incident at the JFK Presidential Library was likely a mechanical fire and no deaths or injuries are being reported.

- The New York Post alleged that a 'Saudi national' was in custody as a suspect in the bombings. Those reports appear to have been wildly inaccurate. Boston authorities have confirmed no suspect has been arrested.

- As many as 90 people may have been injured, with most news sources claiming at least two are dead. Horrific injuries have been reported, including severed limbs and shrapnel damage. WBUR News reports 100 casualties (injuries, not deaths) and 8-10 children severely injured.

- Boston cell phone service was disabled to prevent the detonation of a theoretical subsequent device. It is unclear when service will be active again, though it may already be.
