2004 Madrid train bombings

The 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. 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,^[4][5] although no direct al-Qaeda participation has been established.^[6][7][8] Though they had no role in the planning or implementation, the Spanish miners who sold the explosives to the terrorists were also arrested.^[9][10][11]
