Terror Attack at the Boston Marathon - 2013

BOSTON — Two powerful bombs exploded near the finish line of the Boston Marathon on Monday afternoon, killing three people, including an 8-year-old child, and injuring more than 100, as one of this city’s most cherished rites of spring was transformed from a scene of cheers and sweaty triumph to one of screams and carnage.

Almost three-quarters of the 23,000 runners who participated in the race had already crossed the finish line when a bomb that had apparently been placed in a garbage can exploded around 2:50 p.m. in a haze of smoke amid a crowd of spectators on Boylston Street, just off Copley Square in the heart of the city. Thirteen seconds later, another bomb exploded several hundred feet away.
