On 31 July 2006, two men placed two suitcases filled with bombs on regional commuter trains in Germany. Departing from the central station in Cologne, the bombs were timed to go off near Hamm or Dortmund and near Koblenz, and according to German investigators "would have resulted in the deaths of hundreds of people ... on a much larger scale than the terrorist attacks on London subways and buses in July 2005." However, due to faulty construction, the bombs only failed to ignite, even as the detonators worked. According to the German prosecutor, at the time Germany had "never been closer to an Islamist attack than in this case."
