A fixed camera at IDG's Boston offices captured the moment two explosions rocked the finish line of today's Boston Marathon. The camera shakes slightly and then smoke envelopes the view at about the 15-second mark of the video, which runs 1:48.
After the smoke clears at about the 34-second mark, people can be seen running down Boylston Street in Boston.
According to law enforcement officials, two people were killed and more than two dozen were injured by the blasts, which occurred about 2:50 p.m.
