BARCELONA, Spain — As the terrorism suspects congregated in the largely Pakistani neighborhood here over the past few months, they were joined by a young man who called himself Asim. He had come from the Pakistani borderlands where the leadership of Al Qaeda is said to have regrouped.
The suspects, he later told Spanish investigators, envisioned a wave of spectacular attacks: Coordinated suicide bombings would start in this city’s vast subway system and then sweep through Portugal, Germany, France and Britain if certain demands were not met.
Asim had been sent to Spain to be a suicide bomber, but he also was an informant for French intelligence working in the no man’s land of Waziristan in Pakistan. After he got word to his handlers of an impending attack, Spain’s military police swooped into the neighborhood of Raval in the early hours of Jan. 19 and arrested 14 men. Now the officials unraveling the case say it demonstrates the growing threat of terrorist activities migrating to Continental Europe from Pakistan.
