BOSTON (AP) - Two bombs exploded near the finish of the Boston Marathon this afternoon, killing two people, injuring more than 100 others and sending authorities rushing to aid wounded spectators, race organizers and police said.
One runner, a Rhode Island state trooper, said he saw at least two dozen people with very serious injuries, including missing limbs.
About two hours after the winners crossed the line, there was a loud explosion on the north side of Boylston Street, just before the photo bridge that marks the finish line. Another explosion could be heard a few seconds later.
In this image from video provided by WBZ TV, spectators and runners run from what was described as twin explosions that shook the finish line of the Boston Marathon, today in Boston.
The Boston Marathon said that bombs caused the two explosions and that organizers were working with authorities to determine what happened.
Competitors and race volunteers were crying as they fled the chaos. Bloody spectators were being carried to the medical tent that had been set up to care for fatigued runners. Authorities went onto the course to carry away the injured while stragglers in the 26.2-mile race were rerouted away from the smoking site.
Roupen Bastajian, a 35-year-old state trooper from Greenville, R.I., had just finished the race when they put the heat blanket wrap on him and he heard the first blast.
"I started running toward the blast. And there were people all over the floor," he said. "We started grabbing tourniquets and started tying legs. A lot of people amputated. ... At least 25 to 30 people have at least one leg missing, or an ankle missing, or two legs missing."
A Boston police officer was wheeled from the course with a leg injury that was bleeding.
"There are a lot of people down," said one man, whose bib No. 17528 identified him as Frank Deruyter of North Carolina. He was not injured, but marathon workers were carrying one woman, who did not appear to be a runner, to the medical area as blood gushed from her leg.
Smoke rose from the blasts, fluttering through the national flags lining the route of the world's oldest and most prestigious marathon. TV helicopter footage showed blood staining the pavement in the popular shopping and tourist area known as the Back Bay.
A third explosion was heard about an hour after the first two after authorities warned spectators to expect a loud noise from a water cannon.
