The 2004 Madrid Train Bombings (11-M)

Ten bombs exploded aboard four packed commuter trains during Madrid's morning rush hour. The attacks killed 191 people and injured more than 1,800, leading to a vast investigation, a five-month criminal trial and later Supreme Court review.

The morning of March 11

On the morning of March 11, 2004, coordinated explosive devices detonated on four commuter trains carrying passengers into Madrid. The attacks struck during rush hour and killed 191 people, while more than 1,800 were injured.

The scale of the attack created one of the largest terrorism investigations in modern Spain. Investigators traced the explosives, communications and logistical links around the bombing cell. Several men regarded as central participants died on April 3, 2004, when an explosion occurred in a Leganés apartment as police closed in, so they never stood trial for the train bombings.

The investigation and the ETA claim

In the immediate aftermath, public controversy developed over whether the Basque separatist organization ETA had been responsible. The later criminal judgment did not establish an ETA role. Reporting from the 2007 verdict states that the court found no evidence supporting an ETA connection to the attacks.

That distinction is important because political claims made during an unfolding investigation are not equivalent to judicial findings. This file follows the evidence and verdicts produced in the criminal proceedings rather than later conspiracy narratives.

The 2007 mass trial

The trial began in February 2007 and heard months of testimony and forensic evidence. On October 31, 2007, the Audiencia Nacional found 21 of the 28 defendants guilty of at least one offense and acquitted seven. The convictions were not uniform: some defendants were convicted of terrorist murders and attempted murders, while others were convicted of lesser offenses such as membership in a terrorist organization, weapons or explosives crimes.

Jamal Zougam, Othman el-Gnaoui and José Emilio Suárez Trashorras received the largest nominal prison terms. Under Spanish sentencing rules applicable to the case, however, the effective time to be served was subject to a maximum limit rather than the literal tens of thousands of years produced by adding individual sentences.

The court also acquitted several people who had faced serious allegations, including Rabei Osman Sayed Ahmed. Those acquittals are part of the case outcome and must not be erased by describing every person who stood trial as a convicted bomber.

The Supreme Court changes the result

The 2007 judgment was not the final word for every defendant. In July 2008, Spain's Supreme Court overturned the convictions of four people who had been convicted at the original trial. It also upheld the acquittal of Rabei Osman and changed other parts of the judgment.

At the same time, the Supreme Court overturned Antonio Toro's acquittal on an explosives-related charge and convicted him of that offense. Othman el-Gnaoui was cleared of one lesser falsification charge while his more serious convictions remained in force.

For that reason, the case cannot accurately be summarized simply as “21 final convictions.” Twenty-one defendants were initially convicted in 2007, but the Supreme Court review changed that landscape in 2008.

Suárez Trashorras and the effective sentence

José Emilio Suárez Trashorras, a former miner linked to the supply of explosives, remained one of the central convicted defendants. In a later official notice dated May 3, 2017, Spain's General Council of the Judiciary reported that the Supreme Court rejected his request to apply the newer permanent-reviewable-prison regime retroactively.

The official notice states that Trashorras had been sentenced to a nominal 34,715 years and that his maximum effective prison service under the sentence was 40 years. The 2017 ruling did not undo the underlying conviction.

What remains legally established

The Madrid train bombings are classified here as solved / adjudicated because the criminal proceedings produced convictions for direct and supporting roles in the attacks, followed by appellate review. That status does not mean every person initially accused was convicted, nor does it mean every investigative question about the wider network was resolved.

The legal record is mixed by design: convictions, acquittals and reversals all form part of the final judicial history. Keeping those distinctions visible is essential in a case involving dozens of defendants and politically charged claims.

Timeline

March 11, 2004: coordinated bombs explode on four Madrid commuter trains, killing 191 people and injuring more than 1,800.

April 3, 2004: several suspected central participants die during the Leganés police operation and never stand trial.

February 15, 2007: the main criminal trial begins.

October 31, 2007: the Audiencia Nacional convicts 21 defendants on varying charges and acquits seven.

July 17, 2008: the Supreme Court overturns four convictions, upholds important acquittals and makes other changes to the judgment.

May 3, 2017: the Supreme Court rejects Suárez Trashorras's request for retroactive application of permanent-reviewable imprisonment.

Current status

The March 11 Madrid train bombings are solved / adjudicated for this archive. The final judicial history includes serious convictions as well as acquittals and appellate reversals. No defendant acquitted or cleared on appeal is presented here as a convicted perpetrator, and the court record does not support attributing the bombings to ETA.
