The 2004 Madrid train bombings (also known in Spain as 11-M) were nearly simultaneous, coordinated bombings against the Cercanías commuter train system of Madrid, Spain, on the morning of 11 March 2004 – three days before Spain's general elections and two and a half years after the September 11 attacks in the United States. The explosions killed 191 people and wounded 1,800. The official investigation by the Spanish judiciary found that the attacks were directed by an al-Qaeda-inspired terrorist cell, although no direct al-Qaeda participation has been established.
