Two explosions rocked the Boston Marathon today, leaving many spectators injured.
CNN reports the bombs exploded near the Boston Marathon finish line on Boylston Street as thousands of people gathered to view the annual race.
"I was turning the corner. I was near the Hynes (Convention) Center. I saw two explosions. I just turned around and ran. It was a fireball -- a huge fireball," one runner told CNN. A viewer uploaded the above photo to Twitter.com. The photo shows a fireball and a plume of smoke just after one of the bombs exploded.
4 injured victims have been taken to a Boston area hospital. CNN reports store fronts blown out and many injured, including a Boston police officer.
Witnesses said victims were lying in the street with missing limbs. A few victims reported hearing loss from the explosions.
NewsCenter 5's Sean Kelly told CNN the impact of the explosions could be felt blocks away. The area is being evacuated.
