Boston Marathon Explosion Video is on Vine

Just saw the explosion captured on vine though it was worth sharing. Two dead in bomb blasts near finish line of Boston Marathon, Boston police say. Area hospitals say at least 49, and as many as 51, are injured. Two explosions happened at about 2:50 p.m. Looks like police are confirming a third explosion at JFK Library and cell phone service is being suspended to try and prevent any more detonations.
