THREE DEAD; INJURY COUNT NOW MORE THAN 130
BOSTON (AP) -- Two bombs exploded in the crowded streets near the finish line of the Boston Marathon on Monday, killing at least three people and injuring more than 130 in a bloody scene of shattered glass and severed limbs that raised alarms that terrorists might have struck again in the U.S.
A White House official speaking on condition of anonymity because the investigation was still unfolding said the attack was being treated as an act of terrorism.
President Barack Obama vowed that those responsible will "feel the full weight of justice."
