Madrid, Spain ? A Spanish judge issued the first indictments in the March 11, 2004, Madrid train bombings, charging 29 people Tuesday with murder, terrorism or other crimes after a probe that uncovered a hornet’s nest of Islamic militancy but no apparent link to al-Qaida.

In a minutely detailed indictment spanning 1,471 pages, Juan del Olmo, the investigative magistrate spearheading the probe, described the birth and workings of a cell of longtime residents, most of them from Morocco and Syria.

Inspired by extremist Islamic doctrine, they are said to have risen up against their adopted homeland to kill 191 people and wound more than 1,700 in the coordinated attacks.

Three of the 29 people indicted were charged with 191 counts of murder and 1,755 counts of attempted murder, and three others with conspiracy to commit those crimes.

The indictment says the cell spent about $120,000 to stage the attacks – everything from buying explosives to renting safe-houses – and caused material damage and civil liability of more than $26 million.

A trial is not expected until next year. In the meantime, del Olmo can continue gathering evidence and handing down more indictments.
