At least two explosions occurred at 2:50 p.m. near the finish line at the Boston Marathon, injuring dozens of spectators.

Eagle-Tribune reporter Jill Harmacinski heard two explosions. She said, “there is blood all over Boylston Street on finish line.”

There are reports of deaths and people who have had their limbs blown off.

The explosion was just before the photo bridge near the finish line and Lenox Hotel and was apparently outside of a building. The explosions were felt blocks away.

Bloody spectators were being carried 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.

The subway has been shut down in the area. Runners are reportedly being diverted from the area.
