2004 Madrid train bombings

Terrorist attack on Madrid's suburban trains

The 2004 Madrid train bombings (also known in Spain as 11M for 11 de marzo) (or 3/11) 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 2,500. The bombings constituted the deadliest terrorist attack carried out in the history of Spain and the deadliest in Europe since the 1988 bombing of Pan Am Flight 103 in Scotland.
