Two explosions at the finish line of the Boston Marathon race have left an unknown number of people injured.

Video and photographs from Boston show a scene of confusion, with emergency services descending on the scene and bloodied spectators being taken to a medical tent.

Margaret Evans a senior journalist at WBUR radio in Boston told the BBC "at this point we just don't know how serious and how many".
