UPDATE 4:36 pm ET: A Federal law enforcement authority confirmed to ABC News this was an intentional bombing, using small portable explosive devices. Boston Police confirmed they have found three more suspicious devices. One has been rendered safe.
Just as I left to pick my daughter up from school today, two explosions “rocked the Boston Marathon finish line at Copley Square” the Boston Herald reports. Several people sustained injuries (including severed limbs that reportedly went flying through the air) and some have died it appears. Images of spectators being hauled away covered in blood are very dramatic, reminiscent for any New Yorker of 9/11.
The cause of the explosions has not yet been identified, though of course officials will investigate to determine if the explosions came from bombs and were a planned act of terrorism. An eye witness just told ABC News that the explosions sounded like bombs and happened five seconds apart.
The Boston Herald describes the scene as “stunned and crying people walking away down Beacon Street.” Many runners had already finished the race before the explosions occurred, but if you’re worried about someone you know who was in the marathon today, you can check on them via this website.
We will keep you updated on this story as it develops.
