Telephone wiretaps and listening devices used against a Milan-based Tunisian operative named Sami Ben Khemais provide investigators with “a trove of fresh information” and help them uncover a European network of Islamist radicals. Ben Khemais fell under surveillance some time after arriving in Italy from Afghan training camps in 1998 and has dealings with other radicals in Germany, Spain, Britain, France, Belgium, and Switzerland. Shortly after 9/11, a German official will say the network of interlocking cells uncovered changes counterterrorist thinking in Europe: “In the past, we had seen some links to Afghanistan, but we saw them as more or less acting here without close connections to al-Qaeda. Now we are seeing more and more links between cells and to al-Qaeda. We are rethinking everything.” The European cells are organized under two umbrellas, Takfir wal Hijra and the Salafist Group for Preaching and Combat (GSPC), and its three leaders are Abu Doha, who will be arrested in London (see February 2001); Mohamed Bensakhria, based in Frankfurt, but arrested in Spain; and Tarek Maaroufi, who is arrested in Belgium. The Milan cell of which Ben Khemais is part and which he finances by drug-trafficking, counterfeiting money and documents, and money laundering, is connected to the “Hamburg cell” that provides three 9/11 hijackers in various ways (see December 1997-November 1998, October 2, 1998, and 2000).
