On April 11, 2006, “In Madrid [Spain], the investigating magistrate Juan del Olmo issued indictments for twenty-nine individuals involved in the March [11] 2004 bombings, and in his nearly 1,500-page report, he discussed at length how the Madrid cell had been influenced by al Qaeda but not directed by it. ‘If it is true that the operative capacity of al Qaeda has lessened in the past few years, it is not noticeable in a sustained decrease in its activity,’ he wrote. ‘From the point of view of the threat, regional networks and local groups have acquired greater importance.’ ”
