2004 Madrid train bombings

The 2004 Madrid train bombings were a series of coordinated, nearly simultaneous 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 193 people and injured around 2,050. The bombings constituted the deadliest terrorist attack carried out in the history of Spain and the deadliest in Europe since 1988. The attacks were carried out by individuals who opposed Spanish involvement in the 2003 US-led invasion of Iraq.
