Bombs are much more commonly used in terror attacks outside of the United States, but there have been exceptions. In 1927, a dynamite attack left 45 dead and 58 injured at a school in Michigan. The 1995 Oklahoma City bombing claimed 168 lives, and three people died in the 2013 Boston Marathon bombings. Countries such as Russia experience far more bomb fatalities. From 2009 to July 2014, Russia saw 0.24 annual deaths per million from bombings with four or more fatalities. Muslims committed all of these attacks. That rate is 2.7 times higher than the death rate from mass public shootings in the United States.
