2004 Madrid train bombings

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. The explosions killed 191 people and injured more than 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. Though they had no role in the planning or implementation, the Spanish miners who sold the explosives to the terrorists were also arrested.
