Two bombs struck near the finish line of the Boston Marathon on Monday, turning a celebration into a bloody scene of destruction.
Boston Police Commissioner Ed Davis said Monday night that the death toll had risen to three. Scores were injured at the scene.
One of the dead was an 8-year-old boy, according to a state law enforcement source.
Hospitals reported at least 144 people are being treated, with at least 17 of them in critical condition and 25 in serious condition. At least eight of the patients are children.
At least 10 people injured had limbs amputated, according to a terrorism expert briefed on the investigation.
Doctors are “pulling ball bearings out of people in the emergency room,” the expert said, suggesting the bombs were designed to propel shrapnel.
