This unbelievable footage courtesy of the Boston Globe at the moment two explosions occurred within a few seconds of one another as runners were crossing the finish line at today's 117th running of the Boston Marathon.

The videographer even exclaims, "We've had an attack!" at 1:01 of the video and, upon turning his camera to those who were injured exclaims, "Oh my god.  Oh my god.  Oh my god." at the 1:22 mark.

WARNING:  Disturbing video and NSFW language
