The headquarters of the Boston Marathon has been shut down after explosions went off near the finish line.
The explosions occurred around 3:00 p.m.
It has been reported that there were at least two blasts heard but there may have been more.
There are at least "dozens" of injuries, according to the Boston Globe's Twitter page.

There are also reports indicating that the explosion was in a trash can.
