BOSTON - Two people were killed and more than 100 people were injured this afternoon as two powerful explosions detonated in quick succession near the Boston Marathon finish line in Boston’s Back Bay section, transforming a scene of athletic celebration into bloody chaos.
The dead included an 8-year-old boy, according to a law enforcement source who was briefed on the investigation.
President Barack Obama promised that whoever planted the explosives would be found and brought to justice.
“We still do not know who did this or why. And people shouldn’t jump to conclusions before we have all the facts,” he told reporters at the White House shortly after 6 p.m. “But make no mistake. We will get to the bottom of this ... Any responsible individuals, any responsible groups will feel the full weight of justice.”
The blast came on Patriots Day, Obama noted, which is a state holiday in Massachusetts that celebrates the beginning of the American Revolution.
Blood and broken glass covered sidewalks in the area where the blasts occurred at about 2:50 p.m. Immediately after the explosions, some of the wounded could be seen to have lost limbs; others lay unconscious.
