Madrid Bombings
From dKosopedia
On March 11, 2004, ten bombs ripped through trains in Madrid, Spain. 191 people were killed and nearly 2000 wounded.
The bombers went on to write a letter endorsing Bush for president, complete with GOP-style culture-war rhetoric:
"Kerry will kill our nation while it sleeps because he and the Democrats have the cunning to embellish blasphemy and present it to the Arab and Muslim nation as civilisation."
