Police say at least three people have been killed in the explosions near the finish line of the Boston Marathon.
Police commissioner Ed Davis confirmed the three deaths but provided no details.
Hospitals reported at least 144 people injured, at least 17 of them critically. The explosions knocked spectators and at least one runner off their feet. Some of the victims lost arms and legs. Other injuries included broken bones, shrapnel wounds and ruptured eardrums.
A former Army medic says the scene at today's Boston Marathon was "more like Baghdad and Bombay than Boston." Bruce Mendelsohn was attending a post-race party in an office building just above the blast site when an explosion knocked him to the floor. He rushed outside and found blood, glass and debris everywhere, and began applying pressure to what he calls "gruesome" wounds.
Police say they have no suspects in custody.

Two explosions at the finish line of the Boston Marathon have resulted in injuries.
Bloody spectators were being carried Monday to the medical tent that had been set up to care for fatigued runners. Police wove through competitors as they ran back toward the course.
"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. A Boston police officer was wheeled from the course with a leg injury that was bleeding.
About three 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.
