The arrests by Spanish police of Syrian-born property developer Muhammed Galeb Kalaje Zouaydi and Algerian boat merchant Ahmed Brahim,
seen in these photos, are offering new insights into the covert network of cash flows that allegedly financed some of Osama bin Laden's worldwide terrorist operations.
Zouaydi's alleged associate, Ghasou al-Arash al-Ghalyoun, also pictured here, was picked up by Spanish police the day after Zouaydi's arrest. (AP Photo/EFE)
