“There are a lot of people down,” said one runner quoted by AP news agency.
The incident reportedly came about three hours after the winners crossed the line.
AP said there was a loud explosion on the north side of Boylston Street, just before the bridge that marks the finish line. Another loud explosion could be heard a few seconds later.
Stragglers heading for the finish line were rerouted away from the smoking site of the blasts.
The Eastern Massachusetts branch of the Red Cross has set up a disaster response centre in the area.
