Explosions at Boston Marathon

Two explosions have rocked the finished line at the Boston Marathon about three hours after the first runners crossed the finish line.

Witnesses reported smelling a sulfur-like smell at the scene of the explosions.

No reports of any deaths from the explosions, but WCVB-TV is reporting “A entire store front has been blow out…with massive numbers of casualties reported on the ground [sic]”.
