The 11March2004Madrid attacks (also known as 11/3, 3/11 and 11-M) were a series of coordinated terrorist bombings against the commuter train system of Madrid, Spain on the morning of 11March2004, which killed 191 people and wounded more than 1,800.
By 23 March, 191 people were confirmed dead (177 at the scene, 13 while under medical care), of whom 12 were yet to be identified; and more than 1,800 were wounded (about 100 remained hospitalised.) Initial reports of 202 deaths were later revised down due to the misidentification of body parts.
On the evening of 11March, Acebes told a news conference that a van, stolen on February 28 and containing several detonators and an Arabic-language cassette tape with Koranic verses, had been found in the town of Alcalá de Henares, where three of the four bombed trains originated and all four stopped.
On 12 March the Spanish went out to the street to protest against the bombings, in a government-organised demonstration to condemn ETA, who at the time were being blamed for the attacks.
On 15 March, Spain's ambassador submitted an unapologetic letter updating the Security Council on the progress of the investigation, repeating that the Spanish government had "the strong conviction" that ETA was involved.
He went on to assert that Prime Minister José María Aznar had known an Islamic group was behind the explosions on 11March, but preferred to blame ETA ahead of the general elections which were due just three days away.
